Texto completo da fonteThe chlorophyll fluorescence (ChlF) is directly related to the photosynthetic process. However, at canopy level this physiological link between fluorescence and photosynthesis may be blurred by structural vegetation changes and geometrical effects linked to interactions between sunlight and the three-dimensional structure of the canopy. Furthermore, much of our knowledge about the relationship between fluorescence and the physiological status of plants come from leaf level studies carried out under laboratory conditions. The physiological significance of ChlF at canopy level and under natural conditions is still a major subject of research and a source of uncertainties in the interpretation of SIF. This doctoral project aims were: 1. To study chlorophyll fluorescence yield at canopy level: we describe a new instrument, Ledflex, which is a micro-LIDAR dedicated to perform continuous measurements of vegetation fluorescence yield. Ledflex has been successfully applied under full sunlight conditions to establish the signature of water-stress on a pea (Pisum Sativum) canopy. Under well-watered conditions the Fs diurnal cycle present an M shape with a minimum (Fmin) at noon which is higher than the fluorescence level observed at predawn (Fo). After several days withholding watering, Fs decreases and Fmin

Texto completo da fonteSun-Induced chlorophyll Fluorescence (SIF) is used as a tool to monitor Gross Primary Production (GPP) across different ecosystems. SIF is important to understand the global carbon cycle under changing climate conditions. However, the use of SIF to probe variations in GPP is challenged by confounding factors (canopy biochemical properties, abiotic factors, etc.). In this thesis, we proposed to use multiple scale measurements (spaceborne with the TROPOMI and MODIS sensors, and ground-based) of SIF, reflectance, GPP, and active chlorophyll fluorescence yield (FyieldLIF), useful to observe the physiological variations of the vegetation. In order, first, to evaluate the strength and the nature of the relationship between GP-SIF and to predict GPP using remote sensing metrics; second, to examine the relationship between FyieldLIF and SIFy (SIF normalized by the photosynthetically active radiation, PAR) and the effects of canopy structure and sun-canopy geometry on SIF signal, and third, to explore the influence of canopy structure, light intensity and abiotic factors on SIF and GPP variations and on their links. We found that the strength and the nature of the links between GPP and TROPOMI SIF, across forty flux sites, depend on sites and vegetation types. Further, combined use of SIF and reflectance from satellite observations predicted over 80% of GPP variations. However, we observed that daily surface reflectance at different bands when taken as a whole outperformed daily TROPOMI SIF in predicting GPP, but the relative importance of variables in the random forest model using SIF and VIs (NDVI, PRI and NIRv) as inputs to predict GPP shows that SIF is the most important variable for predicting GPP. This result indicates that at a broad spatial scale, reflectances could be used to predict GPP and the use of SIF as a proxy of GPP raises the question of whether the physiological information related to photosynthesis contained in SIF could be detected at this scale. Based on top-of-canopy measurements in Fontainebleau-Barbeau, we show that active FyieldLIF was not correlated with passive SIFy at the diurnal timescale due to sun-canopy geometry effects. We also observed that the diurnal patterns in SIF and PAR did not match under clear sky conditions, underlining the effects of shadows on the measured canopy SIF. We also showed that the SIF and the reflectance can be used to predict FyieldLIF, while Φk =SIFy/FyieldLIF (an indicator of the interaction between canopy structure and irradiance geometry) is strongly correlated with reflectance and sun-canopy geometry. The analyses show that the links between GPP and SIF and their variations, resulting from ground-based measurements, depend on the temporal scale considered. More specifically, at the seasonal scale, we observed that variations in GPP, SIF, SIFy and FyieldLIF respond to the structural and biochemical development of canopies and to variations in abiotic factors, especially during the heatwaves in 2022. During these extreme weather conditions, we observed that, on one hand, SIF and VIs (NDVI, NIRv and mNDI), and on the other hand, SIF and PAR are not correlated, while GPP, SIF and FyieldLIF strongly decreased. This indicates that SIF and FyieldLIF can be used to monitor impact on photosynthetic activity under stress conditions, while VIs cannot. This specific response of SIF and FyieldLIF compared to VIs highlights the growing interest in the use of SIF as a proxy of GPP under changing climate conditions. However, at the diurnal scale, the interactions between canopy structure and sun geometry, as well as the light intensity control the variations in SIF and GPP and their links. We strongly recommend the use of the synergy between reflectance, SIF and active fluorescence measurements to better understand the dynamics of SIF and its link to GPP in other vegetation types at the canopy scale

Texto completo da fonte[ES] El pimiento es una hortaliza de extraordinaria importancia económica y social en nuestro país. Lamentablemente, la persistente explotación del suelo, el monocultivo y la intensificación de los procesos de producción, conducen al desarrollo de enfermedades del suelo. Esto unido a los estreses abióticos, principalmente la salinidad de las aguas y del suelo, temperaturas subóptimas y estrés hídrico, puede inducir la aparición de fisiopatias en el pimiento como el Blossom-end rot (BER) y cracking o rajado, inducir senescencia vegetal y disminuir no solo la producción, sino también la calidad del producto. La salinidad y la escasez de agua son unos los mayores problemas medio ambientales a los que tienen que hacer frente los cultivos en el área Mediterránea. Un modo de sortear los estreses bajo el prisma de un manejo integrado o ecológico del cultivo, es la utilización de plantas injertadas como estrategia de adaptación. Aunque se ha producido un notable avance en esta técnica (principalmente en tomate, melón, sandía), en el cultivo del pimiento su utilización es poco frecuente aun. En esta Tesis Doctoral se han seleccionado mediante parámetros fisiológicos diferentes genotipos de pimiento tolerantes al estrés salino e hídrico. Los genotipos seleccionados fueron validados como patrones tolerantes a condiciones de estrés hídrico y salino injertados sobre una variedad comercial mediante el estudio de las respuestas fisiológicas, agronómicas y de la interacción patrón/variedad en ambas condiciones de estrés. De los resultados obtenidos se concluye que los genotipos seleccionados y utilizados como patrones mejoraron la tolerancia de las variedades comerciales a la salinidad, en términos de rendimiento (producción comercial) de frutos comparando con otros patrones comerciales y la variedad sin injertar. Diferentes mecanismos fisiológicos explican la tolerancia al estrés, como la capacidad de mantener el potencial hídrico mediante un ajuste osmótico, estimulación del sistema antioxidante, exclusión o retención de los iones tóxicos salinos (Na+ y Cl-) en las raíces y el mantenimiento de la fotosíntesis que permite mantener las funciones metabólicas de las plantas injertadas y la producción.
[CAT] El pimentó és una hortalissa d'extraordinària importància econòmica i social al nostre país. Lamentablement, la persistent explotació del sòl, el monocultiu i la intensificació dels processos de producció, conduïxen al desenrotllament de malalties del sòl. Açò unit als estressos abiòtics, principalment la salinitat de les aigües i del sòl, temperatures subòptimes i estrés hídric, pot induir l'aparició de fisiopaties en el pimentó com el Blossom-end rot (BER) i cracking, induir senescència vegetal i disminuir no sols la producció, sinó també la qualitat del producte. La salinitat i l'escassetat d'aigua són uns els majors problemes mitjà ambientals als que han de fer front els cultius en l'àrea Mediterrània. Una manera de sortejar els estressos davall el prisma d'un maneig integrat o ecològic del cultiu, és la utilització de plantes empeltades com a estratègia d'adaptació. Encara que s'ha produït un notable avanç en esta técnica (principalment en tomaca, meló, meló d'alger), en el cultiu del pimentó la seua utilització és poc freqüent. En esta Tesi Doctoral s'han seleccionat per mitjà de paràmetres fisiològics diferents genotips de pimentó tolerants a l'estrés salí i hídric. Els genotips seleccionats van ser validats com a patrons tolerants a condicions d'estrés hídric i salí empeltats sobre una varietat comercial per mitjà de l'estudi de les respostes fisiològiques, agronòmiques i de la interacció patrón/variedad en ambdós condicions d'estrés. Dels resultats obtinguts es conclou que els genotips seleccionats i utilitzats com a patrons van millorar la tolerància de les varietats comercials a la salinitat, tant en termes de rendiment (producció comercial) de fruits comparant amb altres patrons comercials i la varietat sense empeltar. Diferents mecanismes fisiològics expliquen la tolerància a l'estrés, com la capacitat de mantindre el potencial hídric per mitjà d'un ajust osmòtic, estimulació del sistema antioxidant, exclusió o retenció dels ions tòxics salins (Na+ i Cl-) en les arrels i el manteniment de la fotosíntesi que permet mantindre les funcions metabòliques de les plantes empeltades i la producció.

Texto completo da fonteFucus vesiculosus L. (Blåstång) är en brunalg som i huvudsak växer i tidvattenzonen i marint vatten men arten klarar också att växa konstant under ytan i det bräckta Bottenhavet. Norska havet och den del av Bottenhavet, där algerna är insamlade i denna studie, har salthalterna 34-35 psu (praktisk salthaltsenhet) respektive 4-5 psu. F. radicans L. Bergström et L. Kautsky (Smaltång) är en nyligen upptäckt art (2005) som har utvecklats i Bottenhavet. F. radicans och Bottenhavets ekotyp av F. vesiculosus växer sida vid sida och har tidigare ansetts vara samma art. Sett till hela Östersjön, så ändras ytans salthalt från 25 till 1-2 psu mellan Östersjöns gräns mot Kattegatt och norra Bottenviken. Den låga salthalten i Östersjön beror på det höga flödet av sötvatten från älvarna och på ett litet inflödet av saltvatten i inloppet vid Kattegatt. Salthaltsgradienten är korrelerad med antalet arter som minskar med minskad salthalt. Östersjön är ett artfattigt hav och de arter som finns är till stor del en blandning av söt- och saltvattenarter. Det finns bara ett fåtal arter som är helt anpassade till bräckt vatten och F. radicans är en av dem. Exempel på miljöskillnader för F. vesiculosus i Norska havet och i Bottenhavet är salthalten, tidvattnet, ljuset och temperaturen. Tidvattnet i Norska havet gör att algerna växlar mellan att vara i vattnet och på land, vilket utsätter algerna för stora ljusskillnader, snabba och stora temperaturväxlingar samt även torka. De alger som växer i Bottenhavet har däremot en jämnare och lägre temperatur, istäcke på vintern och mindre tillgång på ljus eftersom de alltid lever under vattenytan. Skillnaderna i miljön mellan växtplatserna leder till skillnader i fysiologiska anpassningar. Anledningen till att F. vesiculosus och F. radicans valdes som studieobjekt i denna avhandling är att de är viktiga nyckelarter i Bottenhavet. F. vesiculosus och F. radicans är de enda större bältesbildande alger som finns i det artfattiga ekosystemet och de används därför flitigt som mat, gömställe, parningsplats och barnkammare för t.ex. fisk. Att de är nyckelarter gör det angeläget att försöka förstå hur algerna är anpassade och hur de reagerar på miljöförändringar för att få veta hur de kan skyddas och bevaras. F. radicans inkluderades även för att se hur en naturlig art i Bottenhavet är anpassad i jämförelse med den invandrade F. vesiculosus. Marin F. vesiculosus inkluderades för att vara en artreferens från artens naturliga växtplats. Studien visar att det finns fler vattenlösliga organiska substanser (finns vissa organiska substanser som har en proteinskyddande funktion) i den marina ekotypen av of F. vesiculosus än i Bottenhavets ekotyp. Anledningen till detta föreslås vara en anpassning till att växa i tidvattenzonen. Vid lågvatten utsätts F. vesiculosus från Norska havet för starkt ljus, uttorkning, och snabba temperatur- växlingar vilket gör att den kan behöva dessa organiska substanser som skydd mot fria syreradikaler som bildas under lågvattenexponeringarna. F. vesiculosus från Bottenhavet har troligen mist förmågan att syntetisera dessa substanser på grund av anpassning till att hela tiden växa under ytan. Mängden mannitol (socker) är högre i den marina ekotypen av of F. vesiculosus än i Bottenhavets ekotyp. Detta föreslås bero på högre fotosyntetiskt maximum i F. vesiculosus från Norska havet jämfört med ekotypen från Bottenhavet. Skillnaden i fotssyntetiskt maximum är bland annat kopplat till ljus- och salthaltskillnaden på algernas växtplatser. Denna teori styrks av att både fotosyntesen och halten av mannitol ökar i Bottenhavets ekotyp när den behandlas i högre salthalt. Studien visar även att båda ekotyperna av F. vesiculosus samt F. radicans har ett ojämnt förhållande mellan fotosystem II och I (PSII och PSI) med en dominans av PSI. Denna slutsats är baserad på fluorescens emissions mätningar vid 77 K (-196 °C) och mätning av den relativa mängden D1 protein (motsvarar PSII) och PsaA protein (motsvarar PSI). F. vesiculosus från Bottenhavet visar ett emission spektrum som pekar mot en jämnare fördelning av PSII och PSI jämfört med den marina ekotypen och F. radicans. Detta stämmer dock inte med förhållandet mellan D1/PsaA som indikerar att alla tre har mer PSI än PSII. Förklaringen till avvikelsen mellan metoderna antas vara att F. vesiculosus från Bottenhavet har större ljus-infångande antennpigment än marin F. vesiculosus och F. radicans. De tydliga skillnaderna i 77 K fluorescens emission spektra mellan Bottenhavets F. vesiculosus och F. radicans visar att denna metod kan användas som säker artidentifiering. Den marina ekotypen av F. vesiculosus har högre fotosyntetiskt maximum än de båda arterna från Bottenhavet. Mätningar av den relativa mängden av enzymet Rubisco, viktigt för upptaget av koldioxid hos växter och alger, visar att mängden enzym är en sannolik förklaring till skillnaden i fotosyntetiskt maximum mellan den marina ekotypen av F. vesiculosus och F. radicans och detta är troligen en normal artskillnad. Mängden Rubisco kan dock inte förklara skillnaden i fotosyntetiskt maximum mellan de båda ekotyperna av F. vesiculosus. För att undersöka vad skillnaden mellan dessa två beror på så föreslås istället mätningar av Rubisco’s koldioxidfixeringshastighet. Det är en ökning av fotosyntetiskt maximum i Bottenhavets ekotyp av F. vesiculosus när den behandlas i högre salthalt (10, 20 och 35 psu) och det högsta fotosyntetiska maximumet uppmättes i alger som behandlats i 10 psu. Denna ökning beror inte på ökning i den relativa mängden av Rubisco. Ökningen i fotosyntesen speglas dock av en ökning av den relativa mängden PsaA. Detta antas bero på att det behövs mer energi i form av ATP och att en ökning av detta kan ske på grund av att mer PsaA kan driva den cykliska elektrontransporten i fotosyntesreaktionen. Ökat behov av ATP antas bero på en ökning av Rubisco aktiviteten men mätning av aktiviteten krävs för att bekräfta detta.

Texto completo da fonteMolecular imaging became a major tool for the diagnosis and the treatment of cancers. This research field includes different techniques, such as Tomography (CT), Magnetic Resonance Imaging (MRI), Optical Imaging or nuclear Imaging (PET Positron Emission Tomography, SPECT Single Photon Emission Computed Tomography). Each imaging modality has its own strengths and weaknesses, and thus, combining different and complementary systems can overcome inherent limitations associated with any one individual techniques and improve the accuracy of disease diagnosis and enhancing patient management. In particular dual-modality Optical/Nuclear imaging may find important preclinical and clinical applications. One possible approach seeks to fuse the two imaging systems into one molecule (MonOmolecular Multimodality Imaging Agent [MOMIA]) in order to ensure the same biodistribution of the two probes. Our strategy consists in combining a DOTA-like compound allowing complexation of radiometal for nuclear imaging (SPECT or PET) with a bodipy moiety, valuable probe those fluorescent properties can be finely adjusted. The first part of this work is dedicated to the synthesis of bifunctional chelating agents based on macrocyclic polyamines for medical imaging application. These compounds must show excellent coordination properties towards the aimed radiometal and possess a grafting function to allow the coupling with a biomolecule. Powerful and general routes for the synthesis of a wide range of N- and C-functionalized macrocycles derived from cyclen and 13aneN4 are described, which enable to access to a wide range of new BFCs by introduction of different functional groups reactive towards primary amines, such as carboxylic acid, isothiocyanate or anhydride function. Some compounds were conjugated to different biomolecules, such as peptides or antibodies. Morever, the introduction of an alkyne function yields a novel family of bifunctional agents allowing chemoselective attachment to functionalized biomolecules or to modified amino acids using « click chemistry ». In a second part, we focused on the introduction of a bodipy moeity to obtain new bimodal agents for dual Optical/Nuclear imaging. Interestingly, the attachment of the polyaminocarboxylate (DOTA derivative) to the bodipy makes it soluble in water and complexation of different metal cations of interest in the macrocyclic cavity does not significantly alter the luminescence properties of the whole system. In addition, the functionalization of the meso position by using an appropriate linker between the bodipy and DOTA-like units, i.e. a 4-nitrophenylalanine derivative, could provide a new bimodal tag for labeling antibodies or peptides. Optimisation of the second generation bodipy-DOTA, i.e. derivatization reaction to reach the near-IR range or introduction of C-functionalised macrocycles was also investigated

Texto completo da fonteThe present thesis studies ZnO nanoparticles embedded in a mesospheric polyacrylic acid (PAA) matrix synthesized via a hydrolysis protocol. The mesospheric ZnO/PAA hybrid structure was previously proved efficient in emitting visible light in a broad range, which results from the deep-level intrinsic defects in ZnO nanocrystals. To further tune the photoluminescence (PL) spectrum and improve the PL quantum yield (PL QY) of the material, metal-doped ZnO and silica-coated ZnO/PAA are fabricated independently. For ZnO doped with metallic elements, the nature, concentration, size and valence of the dopant are found to affect the formation of the mesospheres and consequently the PL and PL QY. Ions larger than Zn2+ with a higher valence tend to induce larger mesospheres and unembedded ZnO nanoparticles. Doping generally leads to the quenching of PL, but the PL spectrum can still be tuned in a wide range (between 2.46 eV and 2.17 eV) without degrading the PL QY by doping small ions at a low doping concentration (0.1 %). For silica-coated ZnO/PAA, an optimal coating correlatively depends on the amount of TEOS and ammonia in the coating process. The amount of TEOS does not affect the crystal structure of ZnO or the PL spectrum of the material, but high concentration of ammonia can degrade the PAA mesospheres and thicken the silica shell. A thin layer of silica that does not absorb too much excitation light but completely covers the mesospheres proves to be the most efficient, with a drastic PL QY improvement of six times. Regarding the application, the materials suffer from thermal quenching at temperatures high up to 100°C, at which white light emitting diodes (WLEDs) generally operates. However, silica-coated ZnO/PAA induces higher emission intensity at room temperature to make up for the thermal quenching

Texto completo da fontePhototrophic biofilms are an ensemble of photo- and heterotrophic microorganisms which grow attached to every submerged surface of wastewater treatment plants (WWTPs) thanks to the solar energy, which support the photosynthetic processes, and to the constant water flow, which provides a continuous load of inorganic nutrients. Hitherto, the ecophysiology of aquatic phototrophic biofilms from WWTPs has been poorly characterised in culture. The aim of this thesis was to assess the photosynthetic characteristics, photoacclimation and nutrient removal ability of phototrohic biofilms from an Italian WWTP under controlled conditions. This study was part of the PHOBIA EU-Project aimed at developing a unifying model of structure and functioning of aquatic phototrotrophic biofilms. Biofilms were collected from the walls of the sedimentation tank (ST) of the Leonardo da Vinci Airport WWTP, Fiumicino (Rome, Italy) and cultured in an incubator prototype at different irradiance, temperature and flow regime. Effective quantum yield of photosystem II (ΔF/Fm') and Electron Transport Rate versus Irradiance (ETR/I) curves were recorded at initial, active and mature stages of biofilm development by means of a Pulse Amplitude Modulated (PAM) fluorometer, and the chlorophylls, carotenoids and phycobiliproteins quantified to determine the community photosynthetic and photoacclimation ability, and phototrophic biomass variation over time. In order to assess the nutrient removal ability, spectrophotometric methods were used to quantify the total nitrogen (N) and phosphorus (P) content in cultured biofilms. Samples were also fixed for transmission electron microscopy (TEM) and observed to visualise intracellular N and P reserves. Biofilms were able to grow in culture attaining high biomass in the different conditions tested. PAM-fluorescence technique provided a rapid and non-invasive assessment of the photosynthetic performance. ΔF/Fm' was significantly affected by the different conditions tested, with higher values obtained at increasing growth irradiance, low temperature and low flow. Data obtained by ETR/I curves recordings demonstrated the acclimation ability of phototrophs to varying irradiance as further confirmed by the variation of photosynthetic pigments. Spectrophotometric data revealed high N and P concentrations in the biofilms indicating that the two nutrients were rapidly removed from the medium and stored by the biofilms during growth. In addition, low temperature and flow positively influenced P retention in the biofilms. Cyanobacteria and microalgae were actively involved in N and P removal and accumulation as evidenced at ultrastructural level by the occurrence of cyanophycin granules and polyphosphate bodies, respectively. Understanding acclimation processes and nutrient removal dynamics in WWTP phototrophic biofilms is of major importance to the development of alternative and environmentally sound tertiary water treatment exploiting autochthonous communities. On this basis, the following step is represented by the isolation and culturing of species that couple high productivity and nutrient removal efficiency for the laboratory creation of biofilm inocula to be used in the depuration process.

Plasmonische Wellenleiter basierend auf metallischen Nanopartikeln sind vom besonderen Interesse, da sie die Umgehung des Beugungslimits und somit eine Hochgeschwindigkeitskommunikation über kurze Distanzen in immer kleiner werdenden Schaltkreisen ermöglichen könnten. Allerdings ist die skalierbare und kostengünstige Anordnung von Partikeln eine große Herausforderung und es werden Nahfelduntersuchungen benötigt um plasmonische Interaktionen detektieren zu können.

Im ersten Abschnitt dieser Arbeit werden die beeinflussenden Faktoren dieser Assemblierungsreaktion systematisch untersucht.

Dazu erfolgen hochaufgelöste Nahfeldmessungen der Wellenleiter mittels Elektronenenergieverlustspektroskopie und Kathodolumineszenz-mikroskopie. Die experimentellen Ergebnisse und zusätzlich durchgeführte Simulationen bestätigen eine durch gekoppelte Oberflächenplasmonenmoden induzierte Weitergabe der Energie innerhalb des Wellenleiters. Diese Oberflächenplasmonenmoden werden bei hoher räumlicher und spektraler Auflösung untersucht.

In this research, we report the effect of the initial Ag:In stoichiometry, capping ligand concentration, and reaction temperature on the optical properties of AgInS2 quantum dots (QDs). The fabricated QDs exhibit excellent optical characteristics, including PL quantum yields of up to 22 % and the appearance of an excitonic absorption peak. This is the first reported observation of such a well-defined exciton absorption feature in AgInS2 QDs. Its appearance could indicate a relatively narrow size distribution or minimization of nonradiative recombination at the surface sites of the QDs. Moreover, we report one-pot two-step synthesis of highly luminescent AgInS2-ZnS QDs by injection of ZnS precursors directly into the same reactor with existing AgInS2 cores without any purification. In addition, to demonstrate their potential biomedical application, the AgInS2-ZnS QDs were coated with poly(maleic anhydride-alt-1-octadecene) and further conjugated with folic acid for human liver carcinoma (HepG2) tumor cell labeling. The folate-receptor-mediated cellular uptake of the folic-acid-conjugated AgInS2-ZnS QDs was confirmed by confocal imaging characterization. Additionally, the small dimensions and high solubility of the folic-acid-conjugated AgInS2-ZnS QDs were also exploited in prefixed-cell staining; the QDs entered the complex cellular matrix and stained both the nucleoli and cytoplasm of HepG2 cells.

In the application of the white LED product, if the local LEDs have different hue and brightness, it will cause chromatic aberration. This problem arises in the production process of white light-emitting diode. Because the batch production caused delay time, and spit gum fixture different ways, affect the speed of phosphor deposition rate, resulting in production of products irregularity, so when the feed of each LED dies are hoping to have the same specification, so more easy to color control within a certain range, and maintain a certain production yields, but doing so will result in increased costs. This paper mainly discusses the part after the phosphors was added into the paste, due to the effect of gravity, and the time difference before and after the operation, the device will result in different CIE offset problems. Although shorten the time difference can be reduced, but will result in increased production costs, the problem cannot be mass-produced. In order to solve the problem of CIE offset, that does not affect the status of production operations situation assessment increase plastic material viscosity, in order to achieve the anti-sedimentation, reduce different phosphor particles settling time difference, and does not affect the product luminous efficiency & quality, and expand plastic material viscosity, improve production yield quality.

Since the discovery in 2004, fluorescent carbon nanodots (FCNDs) have received wide attention due to their excellent biocompatibility and fluorescence. The fluorescent property enables FCNDs to be applied to bioimaging, biosensing, and photocatalysis. To effectively increase the quantum yield (QY) of FCNDs has been an issue of study. The hydrothermal method is widely used to synthesize FCNDs because of simple operation among other methods such as laser ablation and microwave heating. The basic principle of the hydrothermal method is to put the precursor of carbon dots with additives in water and under high temperature and pressure to induce multiple chemical reactions such as carbonization and polymerization. In this study we prepared high QY FCNDs by the hydrothermal method with sulfuric acid as an additive which promotes carbonization. Through the UV absorbance and fluorescence intensity obtained from the UV-Vis and fluorescence spectra, the QY of FCNDs can be calculated. Results show that QY can be increased by 50–100% by adding a small amount of sulfuric acid. The preferred case in this study is that the highest QY (17.6%) can be reached by adding 0.03 ml sulfuric acid to the HEDTA solution. In addition, result of dynamic light scattering analysis and atomic force microscope imaging, the aforementioned FCNDs has an average particle diameter of 8.47 nm.

This thesis is composed of two major parts. First part, we introduced fluorene core to synthesize three new high photoluminescence (PL) quantum yield red/NIR fluorescent molecules. Second part, we designed a new water-soluble two-photon absorption (TPA) chromophore. Over the last few decades, TADF-type organic light-emitting diodes (OLED) is rapidly expanding, and the internal quantum efficiency (IQE) has already reached to 100%. However, it is difficult to design a red/NIR TADF molecule with high PL quantum yield and good light color purity. In this research, we designed three new high PL quantum yield red/NIR fluorescent molecules NZDFT, NZDSF and BBTDSF, and used as dopants dispensed in the TADF exciplex host. The red/NIR emitting devices were obtained external quantum efficiencies (EQE) of 6.89%、12.44% and 0.99%, respectively. Two-photon absorption (TPA) process is a nonlinear absorption process, which absorbs two photons simultaneously. TPA chromophores have wide applications such as fluorescence microscopy and microfabrication. Therefore, in order to increase molecular TPA cross section and tune the position of the TPA peak wavelength, it is a urgent issue to unveil the structure-property relationship with new TPA molecules. In this research, we designed a new water-soluble TPA molecule BTDFNCOOH (σ = 188 GM at 780 nm) with emission peaked at 597 nm in the water (PLQY<5%).
