Abstract:
In the last decade, the field of lanthanide doped upconverting nanoparticles has vastly matured, progressing from the basic understanding of the photophysical properties governing their nanoscale luminescence, to their use in the study of a number of fundamental properties and ultimately to a plethora of applications, with considerable focus in biology and medicine. This interest stems primarily from the ability to stimulate these luminescent nanoparticles with near-infrared (NIR) light as well as their diverse emission wavelengths spanning the UV to the NIR. Therefore, with a single NIR excitation wavelength, it is possible to observe anti-Stokes emission, known as upconversion, or single photon (Stokes) NIR emission. Here, we present our work on the synthesis and surface functionalization of various NIR excited (and emitting) core/shell lanthanide doped nanostructures/nanoplatforms and demonstrate how their various emissions could be harnessed for applications in biology and nanomedicine. Moreover, we investigate how these functional nanoparticles could be rendered even more versatile through rational combination with other NIR excited optical nanostructures.

Abstract:
μNear-infrared (NIR) emissions have been observed in Sm3+doped low phonon energy heavy-metal-gallate glasses. The full-widths at half-maximum (FWHMs) of three fluorescence bands peaking at 960, 1038, and 1185 nm were derived to be 31, 36, and 42 nm, respectively, and the spontaneous transition probabilities were calculated to be 66, 16, and 6 s-1. Maximum stimulated emission cross-sections ( σem) for NIR transition emissions were obtained to be 4.22´10-22, 1.37´10-22, and 0.71´10-22cm2, respectively. Investigations on multi-channel NIR transition emissions of Sm3+, especially on the ~1.19 μm emission, which lies in the low-loss wavelength region of transmission window, are beneficial for potential applications in infrared optoelectronic devices.

Abstract:
An electrothermal fountain is used to heat gas-phase samples in the range of 300 to 400°C in order to observe their near-infrared (NIR) emissions. In conjunction with the fountain, a 1/8-m Ebert monochromator and an uncooled PbS detector are shown to be sufficiently sensitive for recording the NIR fingerprints of CH4, CO2, N2O, and C2H6. At fountain temperatures of approximately 400°C, the molecular emission is confined to the long wavelength NIR region (1600–2500 nm) and yields limits of detection in the range of 4 to 10% v/v (3–10 mg/s). Reproducibilities have relative standard deviations of 3.0%. The calibration curves for the gases examined in this study have small linear dynamic ranges (factors of 2 to 10) and exhibit some degree of upward curvature. Ramifications of the application of NIR molecular emission spectroscopy to the qualitative and quantitative analyses of mixtures are discussed.

Abstract:
The Bi/Sn-doped aluminosilicate glass samples were prepared using a melting–quenching method and their near-infrared (NIR) emission properties were studied. An ultra-broadband NIR emission ranging from 950 nm to 1600 nm was observed in all samples under 480 nm excitation, which covered the whole fiber low-loss window. The NIR emission spectrum showed that the maximum emission peak was about 1206 nm and the full width at half maximum (FWHM) was about 220 nm. Furthermore, the NIR emission intensity strongly depends on the composition of the glass, which can be optimized by modulating the glass composition. The Bi0 and Bi+ ions were the NIR luminescence source of the glass samples in this paper. The Bi/Sn-doped aluminosilicate glass has the potential to become a new type of core fiber material and to be applied to optical fiber amplifiers (OFAs), based on its excellent performance in ultra-broadband NIR emission.

Abstract:
Context. LDN 1642 is a rare example of a star-forming, high-latitude molecular cloud. The dust emission of LDN 1642 has already been studied extensively in the past, but its location also makes it a good target for studies of light scattering. Aims. We wish to study the near-infrared (NIR) light scattering in LDN 1642, its correlation with the cloud structure, and the ability of dust models to simultaneously explain observations of sub-millimetre dust emission, NIR extinction, and NIR scattering. Methods. We used observations made with the HAWK-I instrument to measure the NIR surface brightness and extinction in LDN 1642. These data were compared with Herschel observations of dust emission and, with the help of radiative transfer modelling, with the predictions calculated for different dust models. Results. We find, for LDN 1642, an optical depth ratio τ(250 μm)∕τ(J) ≈ 10−3, confirming earlier findings of enhanced sub-millimetre emissivity. The relationships between the column density derived from dust emission and the NIR colour excesses are linear and consistent with the shape of the standard NIR extinction curve. The extinction peaks at AJ = 2.6 mag, and the NIR surface brightness remains correlated with N(H2) without saturation. Radiative transfer models are able to fit the sub-millimetre data with any of the tested dust models. However, these predict an NIR extinction that is higher and an NIR surface brightness that is lower than based on NIR observations. If the dust sub-millimetre emissivity is rescaled to the observed value of τ(250 μm)∕τ(J), dust models with high NIR albedo can reach the observed level of NIR surface brightness. The NIR extinction of the models tends to be higher than in the direct extinction measurements, which is also reflected in the shape of the NIR surface brightness spectra. Conclusions. The combination of emission, extinction, and scattering measurements provides strong constraints on dust models. The observations of LDN 1642 indicate clear dust evolution, including a strong increase in the sub-millimetre emissivity, which has not been fully explained by the current dust models yet.

Abstract:
Photothermal therapy operated in the second near-infrared (NIR-II, 1000–1700 nm) window and fluorescence imaging in the NIR-IIb (1500–1700 nm) region have become the most promising techniques in phototheranostics. Their combination enables simultaneous high-resolution optical imaging and deep-penetrating phototherapy, which is essential for high-performance phototheranostics. Herein, carboxyl-functionalized small organic photothermal molecules (Se-TC) and multi-layered NIR-IIb emissive rare-earth-doped nanoparticles (NaYF4:Yb,Er,Ce@NaYF4:Yb,Nd@NaYF4, RENP) were rationally designed and successfully synthesized. Then, high-performance hybrid phototheranostic nanoagents (Se-TC@RENP@F) were easily constructed through the coordination between Se-TC and RENP and followed by subsequent F127 encapsulation. The carboxyl groups of Se-TC can offer strong binding affinity towards rare-earth-doped nanoparticles, which help improving the stability of Se-TC@RENP@F. The multilayered structure of RENP largely enhance the NIR-IIb emission under 808 nm excitation. The obtained Se-TC@RENP@F exhibited high 1064 nm absorption (extinction coefficient: 24.7 L g−1 cm−1), large photothermal conversion efficiency (PCE, 36.9%), good NIR-IIb emission (peak: 1545 nm), as well as great photostability. Upon 1064 nm laser irradiation, high hyperthermia can be achieved to kill tumor cells efficiently. In addition, based on the excellent NIR-IIb emission of Se-TC@RENP@F, in vivo angiography and tumor detection can be realized. This work provides a distinguished paradigm for NIR-IIb-imaging-guided NIR-II photothermal therapy and establishes an artful strategy for high-performance phototheranostics.

Abstract:
The use of near infrared (NIR) light for biomedical photonics in the wavelength region between 800 and 2000 nm, which is called “biological window”, has received particular attention since water and biological tissues have minimal optical loss due to scattering and absorption as well as autofluorescence in this region. Recent development of InGaAs CCD enables observations in this wavelength region. In the present paper, we report development of Yb and Er-doped yttrium oxide nanoparticles (Y2O3:YbEr-NP) which show strong NIR emission under NIR excitation (NIR-NIR emission). We also demonstrate that NIR emission can be observed through swine colon wall. Based on these results, we propose a possible application ofY2O3:YbEr-NP for cancer diagnosis and therapy using NIR-NIR imaging system. Our results also suggest potential applications ofY2O3:YbEr-NP for noninvasive detection of various diseases.

Abstract:
The property of persistent luminescence shows great potential for anti-counterfeiting technology and imaging by taking advantage of a background-free signal. Current anti-counterfeiting technologies face the challenge of low security and the inconvenience of being limited to visible light emission, as emitters in the NIR optical windows are required for such applications. Here, we report the preparation of a series of Zn1+xGa2−2xSnxO4 nanoparticles (ZGSO NPs) with persistent luminescence in the first and second near-infrared window to overcome these challenges. ZGSO NPs, doped with transition-metal (Cr3+ and/or Ni2+) and in some cases co-doped with rare-earth (Er3+) ions, were successfully prepared using an improved solid-state method with a subsequent milling process to reach sub-200 nm size particles. X-ray diffraction and absorption spectroscopy were used for the analysis of the structure and local crystal field around the dopant ions at different Sn4+/Ga3+ ratios. The size of the NPs was ~150 nm, measured by DLS. Doped ZGSO NPs exhibited intense photoluminescence in the range from red, NIR-I to NIR-II, and even NIR-III, under UV radiation, and showed persistent luminescence at 700 nm (NIR-I) and 1300 nm (NIR-II) after excitation removal. Hence, these NPs were evaluated for multi-level anti-counterfeiting technology.

Abstract:
AbstractThe measurement of near-infrared (NIR) cathodoluminescence (CL) with sufficient sensitivity to allow full spectral mapping has been investigated through the application of optimized grating spectrometers that allow the ultraviolet (UV), visible, and NIR CL spectra to be measured simultaneously. Two optical spectrometers have been integrated into an electron microprobe, allowing simultaneous collection of hyperspectral CL (UV-NIR), characteristic X-rays, and electron signals. Combined hyperspectral CL spectra collected from two natural apatite (Ca5[PO4]3[OH,F]) samples from Wilberforce (Ontario, Canada) and Durango (Mexico) were qualitatively analyzed to identify the emission centers and then deconvoluted pixel-by-pixel using least-squares fitting to produce a series of ion-resolved CL intensity maps. Preliminary investigation of apatite has shown strong NIR emissions associated primarily with the rare-earth element Nd. Details of growth and alteration were revealed in the NIR that were not discernable with electron-induced X-ray mapping. Intense emission centers from Nd3+ and Sm3+ were observed in the spectra from both apatites, along with minor emissions from other 3+ rare-earth elements. Quantitative electron probe microanalysis was performed on points within the mapped area of the Durango apatite to produce a calibration line relating cathodoluminescent intensity of the fitted peak centered at 1,073 nm (1.156 eV) to the Nd concentration.

Abstract:
Tris(3,5-dimethylpyrazolyl)arsane (1) is introduced as an low-cost and convenient to handle arsenic precursor for the straight forward synthesis of InAs quantum dots (QDs). Transamination of 1 with the solvent oleylamine (OLAH) gives trioleylarsane (As(OLA)3) which in the presence of the reducing agents DIBAL-H or P(OLA)3 yields InAs QDs via a typical hot injection approach. The size of the obtained InAs core QDs are tuned by varying the reaction time, the amount of the applied reducing agent, or even more effectively by changing the indium and/or zinc halide precursors, InX3 and ZnX2 (Cl, Br, or I). Passivation of the resulting InAs particles with a protective ZnS or ZnSe shell results in improved photoluminescence (PL) of the core/shell QDs covering a spectral range between 600–1150 nm.

Full text
Abstract:
In the last decades, cyclometalated Ir(III) complexes have drawn a large interest for their unique properties: they are excellent triplet state emitters, thus the emission is phosphorescent in nature; typically high quantum yields and good stability make them good candidates for luminescent materials. Moreover, through an opportune choice of the ligands, it is possible to tune the emission along the whole visible spectra. Thanks to these interesting features, Ir(III) complexes have found different applications in several areas of applied science, from OLEDs to bioimaging. In particular, regarding the second application, a remarkable red-shift in the emission is required, in order to minimize the problem of the tissue penetration and the possible damages for the organisms. With the aim of synthesizing a new family of NIR emitting Ir(III) complexes, we envisaged the possibility to use for the first time 2-(1H-tetrazol-1-yl)pyridine as bidentate ligand able to provide the required red-shift of the emission of the final complexes. Exploiting the versatility of the ligand, I prepared two different families of heteroleptic Ir(III) complexes. In detail, in the first case the 2-(1H-tetrazol-1-yl)pyridine was used as bis-chelating N^N ligand, leading to cationic complexes, while in the second case it was used as cyclometalating C^N ligand, giving neutral complexes. The structures of the prepared molecules have been characterised by NMR spectroscopy and mass spectrometry. Moreover, the neutral complexes’ emissive properties have been measured: emission spectra have been recorded in solution at both room temperature and 77K, as well as in PMMA matrix. DFT calculation has then been performed and the obtained results have been compared to experimental ones.

Abstract:
L’imagerie de fluorescence et l'imagerie photo-acoustique (PA) sont deux outils puissants pour la visualisation des tissus et organes biologiques de manière non invasive. Toutefois, ces technologies sont actuellement limitées par le manque d'agents de contraste efficaces. Utiliser des longueurs d’onde de domaine du proche infrarouge (NIR, 650-900 nm), dont l'absorption et la diffusion dans les organismes est relativement faible, permet une imagerie in vivo plus profonde, induit moins d’auto-fluorescence et apporte un bon rapport signal/bruit. Par conséquent, la conception et la synthèse de nouveaux colorants organiques NIR efficaces revêt une importance fondamentale pour l’imagerie de fluorescence ou photo-acoustique. L'encapsulation de colorants organiques dans des nanoparticules dispersibles dans l'eau présente un grand potentiel en imagerie bio-optique, offrant les avantages d'une haute luminosité, d'une bonne photo-stabilité, d'une excellente biocompatibilité et d'une capacité potentielle de ciblage, etc. Notre objectif principal dans cette thèse est de synthétiser de nouvelles molécules organiques pouvant servir d’agents de contraste pour l'imagerie in vivo par fluorescence ou PA
Fluorescence and photoacoustic (PA) imaging are both powerful tools for visualization of biological tissues and organs in non-invasive ways. However, these technologies are limited by the lack of efficient contrast agents. NIR light (650-900 nm) with relatively low absorption and scattering in organisms allows for deeper in vivo imaging, lower auto-fluorescence as well as a good signal to noise ratio. Hence, design and synthesis of efficient NIR organic dyes are of great significance for fluorescence or PA bio-imaging. Meanwhile, encapsulation of organic dyes in nanoparticles dispersible in water present great potential in bio-optical imaging, offering the advantages of high brightness, good photo-stability, excellent biocompatibility and potential targeting ability, etc. Our main goal in this thesis is to synthesize novel organic contrast agents for in vivo fluorescence or PA imaging

Abstract:
This work is mainly focused on the investigation and processing of luminescent molecular complexes of lanthanide ions (Ln), for the development of efficient near infrared (NIR)-emitting materials. In the light of a detailed understanding of the chemical/photophysical properties of the special class of lanthanide quinolinolato complexes, as prototype molecular materials for NIR applications, two main aspects have been taken into consideration for a progress in this field: i) (multi-) functional NIR-emissive heterolanthanide complexes and ii) lanthanide-doped sol-gel glasses as NIR-emissive optical materials. Heterometallic assemblies, containing two or more different lanthanide cations as carriers of distinctive functionalities, represent promising materials where different physical properties can coexist or be in interplay thanks to intermetallic communication. A thorough discussion on heterolanthanide assemblies, pointing out the general strategies to achieve the desired (multi-) functionalities in these systems, is provided herein. In this framework, heterolanthanide Er/Yb systems have attracted significant interest for Er3+ sensitization through resonance energy transfer (RET) from Yb3+ leading to enhancement of Er3+ NIR emission at 1.5 μm in glass host Yb-Er co-doped optical fiber amplifiers. A strategy to achieve composition control and homogeneity in such materials resorts to the encapsulation of Er and Yb in the same molecule to afford intermetallic communication between lanthanide ions sitting at short distance in a discrete polynuclear architecture. Fully efficient Yb-to-.Er RET at molecular level is firstly demonstrated in the mixed-lanthanide Yb2ErQ9 complex (Q = quinolinol ligand), and, as an extension of these studies, the investigation of the full photocycle leading to narrow-band NIR emission in a series of heterolanthanide ErxYb3-x quinolinolato compounds, on variation of metal composition and molecular stoichiometry, has been performed. Moreover, the first example of a tri-lanthanide discrete polynuclear molecule containing three NIR-emissive lanthanide ions: Nd3+, Yb3+ and Er3+, is presented. The NdYbErQ9 complex was investigated as a potential broad-band NIR emitter where the intensities of the three different main emissions from each lanthanide ion can be finely tuned on varying metal composition. The investigation of the processing potential of luminescent lanthanide complexes through doping into inorganic or polymeric host matrixes is of crucial interest for the development of optical devices (amplifiers, optical waveguides, OLEDs, etc.). To this purpose, studies on the incorporation of an Yb quinolinolate complex into a silica sol-gel glass, with a thorough account of the photophysical properties of this hybrid material, have been performed. Promising results on silica thin films doped with heterolanthanide Er/Yb quinolinolates are also presented as a molecular approach to achieve controlled light conversion in NIR-emissive optical materials.

Abstract:
In Racing Toward Zero, the authors explore the issues inherent in developing sustainable transportation. They review the types of propulsion systems and vehicle options, discuss low-carbon fuels and alternative energy sources, and examine the role of regulation in curbing emissions. All technologies have an impact on the environment, from internal combustion engine vehicles to battery electric vehicles, fuel cell electric vehicles, and hybrids-there is no silver bullet. The battery electric vehicle may seem the obvious path to a sustainable, carbon-free transportation future, but it's not the only, nor necessarily the best, path forward. The vast majority of vehicles today use the internal combustion engine (ICE), and this is unlikely to change anytime soon. Improving the ICE and its fuels-entering a new ICE age-must be a main route on the road to zero emissions. How do we go green? The future requires a balanced approach to transportation. It's not a matter of choosing between combustion or electrification; it's combustion and electrification. As the authors say, "The future is eclectic." By harnessing the best qualities of both technologies, we will be in the best position to address our transportation future as quickly as possible.

Abstract:
Abstract We present results using near-infrared (NIR) cameras to study emission. characteristics of common defect classes for integrated circuits (ICs). The cameras are based on a liquid nitrogen cooled HgCdTe imaging array with high quantum efficiency and very low read noise. The array was developed for infrared astronomy and has high quantum efficiency in the wavelength range from 0.8 to 2.5 µm. For comparison, the same set of samples used to characterize the performance of the NIR camera were studied using a non-intensified, liquidnitrogen- cooled, slow scan CCD camera (with a spectral range from 400-1100 nm). Our results show that the NIR camera images all of the defect classes studied here with much shorter integration times than the cooled CCD, suggesting that photon emission beyond 1 µm is significantly stronger than at shorter wavelengths.

Abstract:
Abstract In this paper, we present a technique for device temperature measurement using spontaneous near infrared (NIR) emission from an Integrated Circuit (IC). By leveraging modeling and data analysis, time-integrated emission measurements are used to estimate the temperature increase due to switching activity inside the channel of CMOS transistors. The non-invasive nature of the technique allows one to reliably monitor the temperature of any device on-chip without the need for circuit modifications or dedicated on-chip sensors and with a higher spatial resolution than thermal cameras. This method has important applications for modeling heat dissipation during early process development, localizing hot spots, calibrating on-chip sensors, etc. In this paper, temperature is estimated by fitting empirical emission data to an emission model that can be solved for device channel temperature.

Abstract:
Abstract Lock-in thermography (LIT), known as a powerful nondestructive fault localization technique, can also be used for microscopic failure analysis of integrated circuits (ICs). The dynamic characteristic of LIT in terms of measurement, imaging and sensitivity, is a distinct advantage compared to other thermal fault localization methods as well as other fault isolation techniques like emission microscopy. In this study, LIT is utilized for failure localization of units exhibiting functional failure. Results showed that LIT was able to point defects with emissions in the mid-wave infra-red (MWIR) range that Photo Emission Microscopy (PEM) with near infrared (NIR) to short- wave infra-red (SWIR) detection wavelength sensitivity cannot to detect.

Full text
Abstract:
Convergent margin-related magmatic deposits hosted by ultramafic-mafic intrusions are becoming an increasingly important global resource of Ni-Cu-PGE. In the northern Canadian Cordillera, a sub-class of ultramafic-mafic intrusions, known as the Alaskan-type intrusions, are hosted within the accreted arc terranes of the North American continental margin. These intrusions have long been recognized for their chromite-associated PGE mineralization potential. However, their potential to host significant Ni-Cu-PGE sulfide mineralization and to be used in efforts to reduce greenhouse gas emissions through permanent carbon mineralization is becoming increasingly studied. This report describes the main lithologies and field relationships observed at the Wrede Creek and Lunar Creek Alaskan-type intrusions in British Columbia during recent fieldwork.

Full text
Abstract:
Despite global recognition of the urgency of climate action and the need to transition to a low-carbon economy, greenhouse gas emissions continue to rise, and adaptation needs remain urgent. For a number of years, there have been calls for greater attention to political economy in tackling climate change and development outcomes. The political economy analysis is important as it can be used to assess the factors that may enable or constrain the implementation of climate change policies and actions and sustain political commitment. A framework can guide the process of political economy analysis, identifying relevant stakeholders, their incentives and motives, and other structural factors. This rapid review summarises several such frameworks specifically aimed at climate governance issues developed in recent years, some of these also include useful guidance and steps on the implementation of the framework. The review focuses strictly on the literature around political economy analyses in relation to climate change. It does not explore the history of and rationale for political economy analysis in development in general, nor the accompanying frameworks or operational How-To guides. Another K4D helpdesk by Lucas (2019) looking at what factors affect the political will of African governments to address climate change highlights a number of political economy frameworks that may also be useful to draw on.

Full text
Abstract:
Since the mid-1980s, the international community has controlled refrigerants that may damage the ozone layer and cause climate change based on several international agreements. In particular, the Montreal Protocol contributed to not only solving the ozone layer depletion problem but also limiting global warming. Given that the global demand for cooling would triple by 2050 and this rise would increase global greenhouse gas emissions significantly, the Montreal Protocol has expanded its regulatory scope to decarbonize the cooling sector through the adoption of the Kigali Amendment. Also, increasing interest in low-carbon cooling has driven the launch of various global initiatives to complement the international agreements and accelerate low-carbon cooling in developing countries. The experience of implementing the Montreal Protocol and its amendments suggests some lessons and insights for making the Kigali Amendment work well. First, each country should develop and enforce national policies aligned with international agreements. Second, financial and technical support mechanisms should be strengthened to facilitate developing countries’ compliance with the Kigali Amendment. Third, along with the improving energy efficiency of cooling, the substances that neither harm the ozone layer nor exacerbate climate change should be used as substitutes for hydrofluorocarbons. Last, the monitoring, reporting, and verification of controlled substances need to be strengthened.

Abstract:
The findings of this study can inform and enable policymakers in improving occupational air pollution, including addressing air pollution, pollution sources and other related issues in the garment manufacturing sector in Cambodia. Such interventions will help to uphold the health of workers as a human right, ensure safe workplaces, and also be beneficial for the country’s economic growth, as a healthy workforce is more productive. While the garment sector serves as Cambodia’s economic backbone and creates much-needed jobs, it is also a highly polluting industry, alongside being regularly implicated for not upholding labour rights. The sector emits pollutants to air from intensive energy use, solid and hazardous waste emissions, noise pollution and wastewater pollution discharge. Despite this, the sector’s environmental impacts in Cambodia, particularly in relation to air pollution, are not well known, and this gap was highlighted in the development of Cambodia’s 2021 Clean Air Plan. Aiming to fill this gap, in cooperation with SEI, the Air Quality and Noise Management Department of the General Directorate of Environmental Protection of Cambodia’s Ministry of Environment conducted a research project to improve understanding of air pollutant emissions from the textile industry and the health impacts on workers in Cambodia’s garment industry. The study drew on in-depth interviews with 323 garment factory workers across 16 factories, interviews with 16 factory owners, and quantitative data to better understand all interviewees’ experiences with occupational air pollution. While the research documented any symptoms related to air pollution, it did not employ medical research to assess the workers’ health status, nor did it attempt to investigate the cost or impact of air pollution on factory production. This policy briefing draws on a longer report prepared by the Ministry of Environment (Chandath, H., Chhay Por, I., Sokyimeng, S., Dana, S., Raksmey, Y. 2023.
