Abstract:
In search of a new way to fabricate graphene-like materials, isostatic graphite targets were ablated using high peak power with a nanosecond-pulsed infrared laser. We conducted dry ablations in an argon atmosphere and liquid-phase ablations in the presence of a liquid medium (water or toluene). After the dry ablation, the SEM images of the target showed carbon in the form of a volcano-like grain structure, which seemed to be the result of liquid carbon ejected from the ablation center. No graphite exfoliation could be achieved using dry ablation. When using liquid phase ablation with water or toluene as a liquid medium, no traces of the formation of liquid carbon were found, but cleaner and deeper craters were observed. In particular, when using toluene as a liquid medium, typical graphite exfoliation was found. We believe that due to the extremely high pressure and high temperature induced by the laser pulses, toluene was able to intercalate into the graphite layers. Between the laser pulses, the intercalated toluene was able to flash evaporate and blow-up the graphite, which resulted in exfoliated graphite. Exfoliated graphite was found on the ablated graphite surface, as well as in the toluene medium. The ablation experiments with toluene undertaken in this study demonstrated an effective method of producing micrometer-sized graphene material. When using water as a liquid medium, no massive graphite exfoliation was observed. This meant that under the used laser conditions, toluene was a better intercalant for graphite exfoliation than water.

Abstract:
Abstract The work presents results on nanosecond laser ablation of nitride ceramics immersed in a liquid medium. AlN and Si3N4 ceramic plates were used targets, and double distilled water was used as a liquid medium. Radiation of a nanosecond Nd:YAG laser system was used in the ablation process with the purpose of studying the influence of the laser fluence and number of pulses on the target surface morphology. The morphology and phase composition of the structured surfaces were explored by scanning electron microscopy and X-ray diffraction measurements, respectively. The optical properties of the obtained colloids were investigated by transmission measurements in the UV-Vis spectral ranges.

Abstract:
Abstract Titanium grade 2 plates were modified by a pulsed nanosecond laser beam. The aim was to determine the surface properties after the machining process in two different liquid media. The samples were processed in distilled water and paraffin oil. It was found that a surface with half-surface roughness values with a number of cracks was formed in distilled water. The presence of water reduced the size of the heat-affected zone.

Abstract:
AbstractGraphene nanosheets were prepared by pulsed Nd:YAG laser ablation of graphite target in H2O under ambient conditions. The synthesized graphene nanosheets were characterized by high resolution transmission electron microscope (HRTEM), X-ray diffraction (XRD), Raman spectroscopy and Selected Area Electron Diffraction (SAED). The obtained structural and morphological analysis confirmed that the graphene nanosheets could be formed in an aqueous medium via one step method where a nanosecond pulsed near-infrared (NIR) laser (λ = 1064 nm) is used to ablate the surface of a pure graphite target. Compared to other used chemical methods to synthesis graphene nanosheets, laser ablation is an easy, versatile, environmental friendly and rapidly growing method for the synthesis of nanostructured materials such as graphene nanosheets. This technique showed normal operation in liquid medium (i.e. water or organic) under ambient conditions. Our study confirmed the great potential of laser ablation in liquid method for the fabrication of graphene nanosheets based nanofluids wich has a potential applicatiuon as a heat transfer fluid.

Abstract:
The catalytic properties of nanoparticles depend on their size, shape and surface/defect structure, with the entire catalyst performance being governed by the corresponding distributions. Herein, we present two routes of mono- and bimetallic nanoparticle synthesis that enable control of the structural parameters, i.e., wet-chemical synthesis and laser ablation in liquid-phase. The latter is particularly suited to create defect-rich nanoparticles. Impregnation routes were applied to prepare Ni and NiCu nanoparticles, whereas nano- and femtosecond laser ablation in liquid-phase were employed to prepare Ni and NiAu nanoparticles. The effects of the Ni:Cu ratio in impregnation and of laser fluence and liquid-medium on laser ablation are discussed. The atomic structure and (surface) composition of the nanoparticles were characterized by electron microscopic (BF-TEM, DF-TEM, HRTEM) and spectroscopic/diffraction techniques (EDX, SAED, XPS, IR), complemented by theory (DFT). The chemically synthesized bimetallic NiCu nanoparticles initially had Cu-rich surfaces, which changed to Ni-rich upon reaction. For laser ablation, depending on conditions (fluence, type of liquid), highly defective, ordered, or core/shell-like nanoparticles were produced. The case studies highlight the specific benefits of each preparation method for catalyst synthesis and discuss the potential of nanoparticles produced by pulsed laser ablation for catalytic applications.

Abstract:
Pulsed laser ablation in liquid, used for nanoparticle synthesis from solid bulk metal targets (a top-down approach), has been a hot topic of research in the past few decades. It is a highly efficient and ‘green’ fabrication method for producing pure, stable, non-toxic (ligand-free), colloidal nanoparticles, which is often challenging using traditional chemical methods. Due to the short time scale interaction between the laser pulses and the target, it is difficult to achieve complete control on the physical characteristics of metallic nanoparticles. Laser process parameters, liquid environment, and external fields vastly effect the shape and structure of nanoparticles for targeted applications. Past reviews on pulsed laser ablation have focused extensively on synthesising different materials using this technique but little attention has been given to explaining the dependency aspect of the process parameters in fine-tuning the nanoparticle characteristics. In this study, we reviewed the state of the art literature available on this technique, which can help the scientific community develop a comprehensive understanding with special insights into the laser ablation mechanism. We further examined the importance of these process parameters in improving the ablation rate and productivity and analysed the morphology, size distribution, and structure of the obtained nanoparticles. Finally, the challenges faced in nanoparticle research and prospects are presented.

Abstract:
Les nanoparticules (NPs) de métaux nobles sont le siège d’un phénomène de résonance plasmon de surface résultant de l’oscillation collective de leurs électrons de conduction sous l’effet d’une onde électromagnétique. Dans le cas de NPs d’or et l’argent, la fréquence de résonance est située dans visible ce qui confère à ces NPs plasmoniques des propriétés optiques uniques. En particulier, la position et l’intensité de la bande de résonance plasmon peuvent varier en fonction de leur taille, leur forme (rapport d'aspect) et de l'indice du milieu hôte. Les possibilités d’applications nécessitent des échantillons purs et de distribution mono disperse. La synthèse des NPs par voie chimique permet de contrôler dans une certaine mesure la forme et la taille des NPs. Elle nécessite cependant l’utilisation d’agents stabilisants qui mènent à une contamination de surface par les résidus de synthèse. Pour limiter cet inconvénient, la technique physique d’ablation laser en milieu liquide est une alternative prometteuse qui souffre cependant d’un manque de contrôle de la forme et de la taille des NPs produites. La forme et la taille des NPs élaborées par ablation laser en milieu liquide (ALML) sont étroitement liées aux trois étapes essentielles du processus : Interaction cible/laser ; Transport de masse ; Interaction laser/NPs en suspension dans le liquide. Afin d’appréhender les mécanismes régissant chacune de ces étapes, il est nécessaire de les étudier séparément. Dans ce travail, nous nous sommes focalisés sur les mécanismes d’interaction entre le faisceau laser et les NPs en suspension dans le liquide. Suivant la densité d’énergie absorbée par les NPs en suspension, celles-ci subissent la fragmentation ou le remodelage. Par la suite nous avons étudié les mécanismes à l’origine du phénomène de la fragmentation. L’évolution de la distribution de forme des NPs lors de la fragmentation des NPs a été étudiée en développant une technique originale et quantitative de spectroscopie optique in-situ. De même, l’évolution de la fraction volumique des NPs au cours de leur élaboration par ALML par spectroscopie optique in-situ est obtenue et analysée. En parallèle aux travaux expérimentaux, nous avons développé des modèles théoriques pour la compréhension des mécanismes de formation des nanoparticules métalliques par ablation laser en un milieu liquide. Une autre étude approfondie sur la modélisation des propriétés optiques et thermiques de l'interaction Laser-Nanoparticules est discutée dans cette thèse. Un modèle thermique de Takami modifié nommé MTM (Modified Takami Model) a été également introduit. Son utilité importante a été démontrée pour l’interprétation des mécanismes de l’interaction laser-NPs
Noble metal nanoparticles (NPs) are the site of a surface plasmon resonance phenomenon resulting from the collective oscillation of their conduction electrons under the effect of an electromagnetic wave. In the case of gold and silver NPs, the resonant frequency is in the visible range, which gives these plasmonic NPs unique optical properties. In particular, the position and intensity of the plasmon resonance depend on their size, shape (aspect ratio) and the index of the host medium. The possible applications require pure samples and mono-dispersed distribution. The chemical synthesis of NPs allows the shape and size of NPs to be controlled. However, it requires the use of stabilizing agents, which lead to surface contamination by synthetic residues. To limit this disadvantage, the physical technique of laser ablation in a liquid medium is a promising alternative, which, however, suffers from a lack of control over the shape and size of the NPs produced. The shape and size of NPs produced by liquid laser ablation (ALML) are closely related to the three essential steps of the process: Target / laser interaction; Mass transport; Laser / NPs interaction suspended in the liquid. In order to understand the mechanisms governing each of these stages, it is necessary to study them separately. In this work, we focused on the mechanisms of interaction between the laser beam and the NPs suspended in the liquid. Depending on the energy density absorbed by the suspended NPs, they undergo fragmentation or remodeling. We then studied the mechanisms behind the phenomenon of fragmentation. The evolution of the shape distribution of NPs during NP fragmentation was studied by developing an original and quantitative technique of in-situ optical spectroscopy. And, the evolution of the volume fraction of NPs during their preparation by ALML by in-situ optical spectroscopy is obtained and analyzed. In parallel with the experimental work, we have developed theoretical models for understanding the mechanisms of formation of metallic nanoparticles by laser ablation in a liquid medium. A modest study on the modeling of optical and thermal properties of the Laser-Nanoparticle interaction is discussed in this thesis. A modified Takami thermal model named MTM was also presented. Its important utility has been demonstrated for mechanisms for the interpretation of the mechanisms of laser-NPs interaction

Abstract:
Particles in the nanometer size range have attracted increasing attention with the growing interest in nanoscience and nanotechnology. They hold potential as basic components for sub-wavelength optical devices, for surface-enhanced spectroscopy, for biological labelling and sensing, and for cancer therapy. For such applications, it is crucial to prepare metal nanoparticles with desired shape, and size distribution. In this context, Pulsed Laser Ablation in Liquids (PLAL) has become a key method for synthesis of nanoparticles with controlled geometry and size.

Abstract:
Lorsqu'une impulsion laser est focalisée sur une cible solide immergée dans un liquide, de la matière est vaporisée. La nucléation et la croissance ont lieu dans le liquide et des nanoparticules sont ainsi synthétisées. La méthode est très polyvalente puisqu'une grande variété de matériaux peut être générée. De plus, les nanoparticules sont directement stabilisées dans le solvant. L'ajout d'agent complexant n'est pas nécessaire mais peut tout de même permettre de mieux contrôler la taille des nanoparticules. Cependant, de nombreux processus sont mis en jeu durant la synthèse et l'objectif de ce travail doctoral est de développer la compréhension de ces éléments. Dans la mesure où l'ablation laser déploie une multitude d'´échelle de temps, il a fallu employer différentes méthodes pour élucider ces mécanismes. Pour commencer, je définirai un état de l'art de l'utilisation de l'ablation laser en milieu liquide et nos résultats concernant la synthèse d'aluminium oxyde dopé chrome. Par la suite, je présenterai la spectroscopie des plasmas et les questions sous-jacentes à la notion d'´équilibre dans un plasma moléculaire. Ensuite, je décrirai notre approche atomistique de la nucléation basée sur les techniques de chimie quantique. Enfin, je montrerai l'apport de l'utilisation des méthodes d'ombrographie pour mieux comprendre la thermodynamique du système au temps plus long. Notre étude démontre que la bulle formée suite à l'ablation laser est constituée essentiellement de molécule du solvant dont la quantité n'évolue quasiment pas au cours du temps de vie de la bulle
When a pulsed-laser is focused into a solid target immersed in water, the material is evaporated. Nucleation and growth occur in the liquid and nanoparticles are synthesized. The method can be considered as versatile because one can try to synthesize any kinds of materials. Also, the nanoparticles are directly stabilized by the solvant so there is no need of complexing agents. The nanoparticles are described as ligand-free. However, various processes can occur during the synthesis and the aim of my work is to understand these different components. Since the laser ablation in liquid displays a wide range of timescales, we used numerous methods to address this problem. First, I will present the use of plasma spectroscopy and the questions it raises towards local thermodynamic equilibrium. Then, I will describe our microscopic approach of nucleation based on quantum chemistry techniques. Finally, I will illustrate the advantages of shadowgraphic measurements to reach an hydrodynamic understanding of the system

Abstract:
The exponential spread of high level technology in the last decade has been followed by an increasing request for new materials able to fulfill all required characteristics for the construction of smaller devices. In this view, nanostructures and in particular metal nanoparticles are gaining attention since their unique optical, electrical and antibacterial properties. Pulsed Laser Ablation in Liquid represents a consolidated route for the synthesis of pure surface metal nanoclusters but, till now, the low production yield of this technique has stopped every attempt in this direction. For these reasons, the development of new strategies to enhance the amount of ablated material represents an interesting field of research. In particular, it has been studied how the ablation of a metal wire in a water flow chamber can lead to an increase of the productivity with respect to bulk ablation and a strong dependence of efficiency on the wire thickness and laser parameters has been noted. A model to describe this behaviour has been proposed, with considerations about heat loss phenomena, reflectivity of the wire surface and cavitation bubble mechanism. Laser fabricated nanoparticles have been also used for the preparation of different nanocomposites in order to tune their properties. Spontaneous and induced aggregation phenomena of noble metal nanoparticles have been studied, with regard to their influence on the Surface Plasmon Resonance variations. It is also possible to combine single metal colloidal solution for obtaining mixed metal nanoparticles with unique features. For this reason, Au/Ni mixed systems have been produced by laser mixing in liquid environment and characterized by spectroscopic and morphological techniques. The mechanism of their formation has been explained on the base of the laser irradiation environment conditions.

Abstract:
Zinc oxide (ZnO) is a wide band-gap semiconductor material (Eg=3.37 eV) characterized by many promising properties which make it appealing for several technological applications. One of the most attractive features is its high exciton binding energy (60 meV) which allows the observation of the UV excitonic emission at room temperature and favors the excitation of defect-related emission bands in the visible spectral region. In recent years, there has been an increasing interest in ZnO nanostructures due to their variety of morphologies and availability of simple and low cost processing methods. Among the techniques currently available, pulsed laser ablation in liquid (PLAL) offers a simple and versatile route to synthesize nanoparticles (NPs) of extremely high purity. In this Thesis we have reported an experimental study on ZnO NPs produced by PLAL providing a complete characterization of their morphological, structural and optical properties, as well as a deep insight on the formation processes involved during the NPs synthesis. Our investigation is founded on the combined use of several experimental techniques including in situ optical absorption (OA) and photoluminescence (PL), and ex situ force microscopy (AFM), high resolution TEM (HRTEM), Raman and time resolved. Microscopic analysis has evidenced that ns PLAL of zinc target in water produces ZnO nanocrystals with an average size of tens of nm having a wurtzite structure. Their UV-Vis absorption curve exhibits the typical edge of wurtzite ZnO and time resolved PL spectra show the corresponding excitonic PL peaked at 3.32 eV with a single exponential lifetime of 800 ps. ZnO NPs display a further PL peaking at 2.2 eV related to defects, which decays following a power law consistent with a recombination mechanisms where trapped electrons tunnel to recombination centers. Thermal annealing in O2 and in a He atmosphere produces a reduction of the A1(LO) Raman mode at 565 cm-1 associated with oxygen vacancies, accompanied by a decrease of defect-related emission at 2.2 eV. Based on our experimental results the emission at 2.2 eV is proposed to originate from a photo-generated hole in the valence band recombining with an electron deeply trapped in a singly ionized oxygen vacancy. In situ analysis has clarified the oxidation process of the ablated Zn, which occurs out of the plume region, due to the reaction of Zn NPs with water molecules. OA spectra exhibit a peak at 5 eV coming from surface plasmonic resonance (SPR) of Zn NPs and the typical absorption edge of the wurtzite ZnO, thus revealing transient Zn/ZnO core-shell NPs, which are fully oxidized only several hundreds of seconds after the end of PLAL. Defect-related PL arises with afurther delay time (100 s) indicating that the earliest oxidation of Zn essentially produces defect-free ZnO. We have also investigated the effects of laser parameters and of the solvent on the oxidation kinetics. The intensity ofthe SPR peak at 5 eV evidences that the Zn/ZnO ratio at the end of PLAL decreases on decreasing the laser repetition rates. Moreover, the oxidation rate of Zn NPs decreases on varying the mixture of water andethanol from 0 to 100%. These findings can be explained considering that initially produced Zn NPs are oxidized in two phases. An earliest and superficial oxidation, and a later and slower oxidation which is sensitive to the repetition rate, and it is completed only after the end of ablation thus leading to the disappearance of the metal species. Overall, our findings enrich the knowledge on the PL origin and dynamics of ZnO NPs useful in view of their use in new applications which exploit the enhancement of surface to volume ratio favoring the formation of luminescent defects as well as increase the material reactivity with the surrounding environment.

Abstract:
De nombreux domaines, tels que le biomédical, la micro-fluidique ou l'optique quantique, sont demandeurs de nanoparticules présentant des propriétés optiques spécifiques. L'ablation laser en liquide, PLAL (Pulsed Laser Ablation induced in Liquid) est une méthode de synthèse permettant d'élaborer rapidement des nanoparticules dans une large gamme de matériaux, et donc de tester la conservation ou la modification des propriétés optiques originales identifiées dans certains matériaux lorsque l'on passe aux tailles nanométriques (scintillation, thermoluminescence, photo-stimulation, haut rendement de luminescence...). Dans ce travail de thèse la synthèse, la caractérisation optique et structurale de nanoparticules dopées a été développé. Différents types de matériaux ont été testés dont l'oxyde de gadolinium dopé, l'yttrium aluminium garnet (YAG), l'alumine etc. Cela a permis de montrer la faisabilité et la potentialité de cette technique d'élaboration sur différents matériaux. Par ailleurs un outil de diagnostic du plasma par spectroscopie optique résolue en temps a été mis en place afin de comprendre les processus des croissances des particules formées.

Abstract:
AbstractLarge amounts of uranium-containing radioactive waste are generated in reactor operation and in the research and manufacture of nuclear fuel elements. At present, there are various uranium enrichment and separation methods such as reduction precipitation method, ion exchange method, solvent extraction method, membrane filtration method, adsorption method, and microorganism method to treat the uranium-containing radioactive waste generated in the related processes of nuclear facilities. However, the airborne effluent or liquid effluent discharged after treatment may still contain radioactive uranium. It is well known that uranium is a radioactive heavy metal element, and its radioactive and chemical toxicity cannot be ignored. Uranium in the environment enters the human body through the food route, and its long half-life can make the human body suffer from continuous radioactive internal radiation damage. As an environmental medium, organisms are closely related to the entry of uranium into the human body through food. Therefore, it is of great significance to carry out accurate measurement of uranium content in environmental-grade biological samples around nuclear facilities, however, complete and accurate measurement results include measurement data and uncertainty. Laser fluorescence method is a method for rapid analysis of uranium content in environmental samples. It has the advantages of high sensitivity, simple sample pretreatment, and wide measurement range, which has been widely used in nuclear industry, environmental monitoring and scientific research. At present, there is a lack of relevant reports on the uncertainty of the measurement of total uranium content in environmental-grade biological samples by laser fluorescence method. It is of great significance to accurately measure the uranium content in biological samples by evaluating the uncertainty of this method. In this paper, the WGJ-III trace uranium analyzer was used to analyze the uncertainty source of total uranium in environmental-grade biological samples by laser fluorescence method. The uncertainty measurement model was established, the uncertainty components were quantified, and the expanded uncertainty of the measurement of total uranium content in environmental biological samples was calculated. The evaluation results showed that the expanded uncertainty of a 0.05 g environmental biological sample is 10.8% (k = 2) without dilution, and the dominant uncertainty component is derived from the measurement uncertainty of sample fluorescence counting.

Abstract:
Abstract Direct laser machining in sub-micron scale patterning at a surface of material remains a challenging task though the laser machining has been widely applied in various application. A photonic nanojet becomes a promising way to solve the problem by involving near-field focusing of light waves below the surface of a dielectric microsphere to fabricate pattern in micro- and nanometer size. By generating laser power to the microsphere and controlling the resulting photonic nanojet intensity distribution and position related to the workpiece, intended ablation size on the material could be controlled at the sub-micrometer scale. In this study, liquid is proposed as photonic nanojet machining medium due to several advantages that liquid offer during machining process. Laser trapping system is then introduced to the optical system to control the position of the microsphere during machining process. An in-liquid nanomachining by generating photonic nanojet in laser trapping configuration is a subject to study with the effect on the resulting ablation and viability of machining process from a set of parameters are investigated numerically using finite-difference time-domain (FDTD) technique. According to the findings of this study, nanometer scale, flexible, and fast novel laser nanomachining could be realized by combining photonic nanojet machining and laser trapping technique.

Abstract:
Abstract The mechanisms of pulsed laser-induced ablation of strongly absorbing solutions and generation of acoustic transients are described in this paper. Aqueous solutions of K2CrO4 are irradiated by a KrF excimer laser (λ = 248 nm, FWHM = 24 ns) with moderate energy density below the plasma-formation threshold. The ablation process including the vapor cavity formation and the acoustic-wave propagation is visualized by laser flash photography. The generated pressure transients are measured using a broadband piezoelectric pressure transducer. Simultaneous optical transmission detection is also carried out in order to elucidate the vapor-phase kinetics. The mechanisms of liquid ablation and acoustic-pulse generation are investigated based on the thermoelastic behavior of the liquid medium and the evaporation dynamics. The results show that the ablation is initiated by cavitation driven by the tensile component of the produced thermoelastic stress. Three distinct stages are identified in the ablation process: the initial stage with negligible surface deformation and ejection of a small amount of vapor, the second stage with violent vapor plume and bulk liquid jet ejection that is accompanied by significant surface deformation, and the final stage of large scale hydrodynamic motion. The pressure transient is generated thermoelastically at low laser fluences, but the contribution of the vapor phase expansion and / or recoil momentum exerted by the ablation plume becomes dominant at high laser fluences.

Abstract:
The fabrication of thin films optical waveguides of photorefractive materials is particularly desirable for applications in integrated optics. It is also of interest because the guided-wave intensity-length product can be considerably larger than in bulk media because of the optical confinement within the waveguide. The increased intensity-length product may therefore allow much faster response times than in the bulk (typically by a factor of ≈103-l04). Thin crystalline films can be fabricated by a variety of techniques such as RF sputtering, flash evaporation, molecular beam epitaxy and liquid phase epitaxy. However, the films grown are often of the incorrect (or variable) composition and phase and are rarely of good optical quality. We discuss here two methods that we have investigated for producing optical waveguides in several different photorefractive materials.
