Повний текст джерелаThis work is devoted to the study of the optical properties of semiconductor and metallic nanostructures. The inelastic light scattering by low frequency acoustic vibrations (AV), called Raman-Brillouin (RB) scattering, gives access to such properties. The confined electronic states of semiconductor nanostructures are involved in the RB scattering as an intermediary. When applying an external electric field, metallic nano-objects sustain collective oscillation modes of the free electron gas (plasmons) which also act as an intermediary during the emission and the absorption of low frequency AV in the RB scattering process. The understanding of the interaction between the AV and the electronic excitations (excitons or plasmons) gives direct information on the optical and vibrational properties of those nano-objects. New physical concepts are introduced as theoretical tools for the interpretation of the RB scattering in semiconductors and metals. An effective electronic density, responsible for the RB scattering in semiconductors, is here introduced for the first time as new advanced theoretical tool for the interpretation of the inelastic light scattering processes by low frequency AV. The concept of acousto-plasmonics is also introduced for the first time to study and describe the modulation of the plasmonic properties of metallic nano-objects by the AV. These concepts and the numerical methods used in this work (BEM, DDA, FDTD) allowed to interpret fine physical effects such as significant spectral red-shifts of plasmons resonances and unexpected observations of AV by RB spectroscopy

Resumo: Este trabalho é dedicado ao estudo dos multiferróicos, um tipo especial de sistema de elétrons fortemente correlacionados. Foram analisadas teoricamente estas substâncias e estudada a família LiMPO4 (M: Mn, Fe, Co, Ni) em particular. Este trabalho focou particularmente no composto de Mn, LiMnPO4, onde foram utilizados os dados existentes e os recém obtidos de espalhamento inelástico de nêutrons (INS), magnetização, espalhamento Raman e ressonância paramagnética eletrônica (ESR) para modelar as interações magnéticas presentes no material. Os resultados obtidos em monocristais deste composto permitem refinar o conhecimento das interações magnéticas do mesmo. O modelo desenvolvido realiza um ajuste simultâneo dos novos dados de espalhamento Raman e os já publicados de INS, mostrando uma clara interpretação do papel dos parâmetros de troca no material escolhido. É esperado que este cálculo seja estendido para toda a família e para outros compostos. Esta tese tenta ser auto-contida, por isso incluiu-se boa parte do material necessário para o leitor e futuros continuadores deste trabalho
Abstract: This work is devoted to the study of an special type of strongly correlated electrons\' compounds, namely the multiferroics. We analyze theoretically those substances, and we study a particular family of them, the LiMPO4 (M: Mn, Fe, Co, Ni) family. We focus particularly in the Mn compound, LiMnPO4, where we use existing and newly obtained data from Inelastic Neutron Scattering, Magnetization, Raman Scattering and Electron Spin Resonance to model the magnetic interactions in the material. The results in single crystals of this compound allow us to refine the knowledge of the magnetic interactions in LiMnPO4. Our model develops a calculation that fits together the new Raman experiments and the already published INS, arriving to a clear interpretation of the role of the exchange parameters in the chosen material. We expect that our calculation will be extended in the future to the whole family and to other compounds. This thesis tried to be self-contained, so we included some material that can be useful for the readers and future continuators of this work

Повний текст джерелаDriven by the interest in finding ultrasensitive sensors devices, reliable surface enhanced Raman scattering (SERS) based substrates are fabricated. Silver and gold nanoparticles are two of the best candidates for SERS substrates where Ag nanoparticles exhibit large enhancing ability in Raman intensity while Au nanostructures are stable in biological systems. Hence, combining the two metals in bimetallic nanostructures appeared to be a promising approach in order to sum the merits of Au surface properties and Ag enhancing ability. Thermal annealing of thin metallic films is used as a simple and relatively inexpensive technique to elaborate homogenous and reproducible Ag/Au bimetallic nanoparticles SERS substrates with high enhancing ability. The fabricated nanoparticles proved their enhancing stability even after one year of fabrication. Manipulating the composition of Ag/Au bimetallic NPs resulted in tuning the Localized Surface Plasmon Resonance (LSPR) over the whole visible spectrum, where the substrates are characterized with higher SERS enhancement when they exhibit LSPR closer to the Raman excitation wavelength. Additionally, bimetallic nanoparticles patterns with different size, composition and lattice constants have been conducted by electron beam lithography. The systematic study of their interesting plasmonic and SERS enhancing properties revealed maintenance in the LSPR-SERS relation by changing the nanoparticle size

Повний текст джерелаIonic liquids (ILs) belong to a broad class of ionic compounds that, differently from conventional salts, are usually liquid at T < 100°C. They are characterized by vanishing vapour pressure, good thermal stability, high ion density and ionic conductivity. Thanks to the large variety of available ions, the physico-chemical properties of ILs can be modulated by careful selection of both cation and anion with specic characteristics for tailored applications. A more convenient strategy for an ecient tuning of the performances of ILs consists in mixing ILs with other ionic or molecular liquids, such as e.g. water. It is observed that addition of water to ILs allows to improve some of their properties and performances, especially for applications in biological eld. For instance, recent studies reported on the capability of IL/water solutions to enhance the structural stability of proteins, enzymes and deoxyribonucleic acid (DNA) also at high temperatures. This PhD thesis aims to show the usefulness of synchrotron-based UV Resonance Raman (SR-UVRR) spectroscopy for investigating i) the structural dynamics of IL/water solutions and ii) the solvation efects of these IL-based solvents on bio-molecules, such as peptides and DNA. UVRR exhibits several advantages with respect to conventional spontaneous Raman spectroscopy, as the signicant increment of the detection limit that allows to study the samples in very high diluted conditions and the selective enhancement of the Raman cross section of vibrations associated to specic molecular groups of the same system. Thanks to the unique tunability of the synchrotron emission, the UVRR spectra of aqueous solutions of imidazolium-based ILs have been excited at diferent wavelengths nely matching with the resonance transitions occurring in the system. These spectra showed to have good sensitivity to the modications induced on the local structure of solutions of ILs by i) the change of the anion and ii) the substitution on the imidazolium ring of progressively longer alkyl-chains. Additionally, some UVRR signals are specically informative on the effect induced by addition of water on the strength of hydrogen bonds (H-bonds) in IL-water solutions. The molecular view provided by SR-UVRR experiments has been further complemented by the structural parameters extracted by Small Angle Neutron Scattering (SANS) measurements performed on the same IL/water mixtures. The investigation of the structure-dynamic relationship in IL/water solutions is the preliminary step for the deep comprehension of the effects of these mixtures on the solvation dynamics of molecules of biological interest, such as peptides and DNA. This is an issue of special interest by considering that the solute-solvent interactions are strongly related to the biological activity of bio-macromolecules. Some results will be presented in this thesis, concerning the case of two different type of bio-systems: i) small peptides dissolved in IL/water solutions: the UVRR spectra of peptides contain several spectroscopic markers of the structural rearrangement induced by the hydration shell on peptides, such as the Amide bands that are usually not well detectable in spontaneous Raman spectra. The analysis of these spectral features can provide insights on the peculiar effect induced on the hydration dynamics of peptides by different ILs; ii) DNA dissolved in IL/water solutions: a suitable choice of the exciting radiation allows to collect UVRR spectra of DNA where the vibrational signals associated to the different nitrogenous bases are selectively enhanced. This gives the unique opportunity to disentangle specic bands in the Raman spectra of DNA that appear usually very complex. Such approach can be conveniently used to obtain insights on the molecular mechanism responsible of the different thermal stability exhibited by DNA structure in the presence of different IL/water solutions.

Повний текст джерелаThe recent advances in nanofabrication techniques have allowed for the emergence of novel sensing approaches. Amongst these various approaches, Surface Enhanced Raman Spectroscopy (SERS) via the use of plasmonic substrates has received wide-spread attention due to its many interesting proper-ties. In fact, plasmonic substrates enhance the Ra-man signal up to 12 orders of magnitude, paving the path for single molecule detection. Nevertheless, the sensitivity of this technique is strongly affected by the physical and structural properties of the metallic nanoparticles (MNPs). Thus, the mastering of the MNPs fabrication is a major challenge for various nanotechnological applications.In this context, we have developed a novel approach for the fabrication of organized NMPs through poly-mer self-assembly. The fabrication technique con-sists on controlling the physical interactions which occur during the fabrication through a nanophase separation in the polymer solution. This results in a nanostructuring of the polymer and a strong self-organization of the metallic precursor which is rapidly reduced into the MNPs. Experimental investigations of the different physical and chemical processes in play allow for a better understanding of the various keystone parameters of the nanostructuring as well as for determining their influences on the dimensions and optical response of MNPs. Finally, the fabricated plasmonic substrate demonstrated SERS limits of detection down to 10-13 M

Повний текст джерелаSignals in optical fibers used for the transfer of information are attenuated due to impurities, scattering, absorption… To compensate for these losses, several techniques were developed like Erbium Doped Fiber Amplifier (EDFA). An alternative to rare earth doped fiber amplifier is Raman Amplification, which results from stimulated Raman scattering. Noble metal nanoparticles have optical properties induced by the collective oscillation of their conduction electrons when they interact with an electromagnetic wave. These particles strongly absorb the electromagnetic field at a frequency called surface Plasmon resonance frequency. This work is mainly based on effects leading to the improvement of the Raman Amplification. The ANR project Fenoptic (2010-2012), gathering Draka and several French laboratories (ICB (Dijon), CMCP (Paris), LPCML (Lyon)) is interested in the integration of noble metal nanoparticles in optical fibers using properties of the surface Plasmon resonance to improve the efficiency of optical amplifiers. In this work, different kinds of samples (suspensions, layers, optical fiber performs) with metal nanoparticles were studied. The experiments were based on the characterization (form and position of the Plasmon band) of noble metal nanoparticles in amorphous matrix and Raman spectroscopy was used to study the Surface Enhanced Raman Spectroscopy (SERS) effect. For the first time, we found the Raman signal exaltation of an amorphous matrix

Повний текст джерелаThe development of single molecule-based techniques in the last decades has enabled directly selecting, tracking, and measuring an individual molecule. In this thesis, the structural dynamics of a single quantum emitter, served by hypericin, is characterized. By using confocal scanning microscopy combined with radially/azimuthally polarized laser modes, three-dimensional reorientation of the transition dipole moment of a single molecule is observed. To quantify the temporal properties of the tautomerism, photon autocorrelation function is used to extract the intensity fluctuations. The results show the distinct influence of the local environment, such as PVA matrix and deuteration effect. The local photonic environment of a molecule is modified by the microcavity/nanocavity. A significant change of the radiative emission rate and of the fluorescence spectra is discussed. It allows us to measure the absolute quantum yield by using a tunable microcavity. The results show the possibility of controlling tautomerization by changing the photonic environment. Subsequently, molecular dissociation is discussed by single molecule surface-enhanced Raman spectra profiting from near field enhancement of nanocavity. A fast experimental optimization strategy towards optimal fluorescence enhancement is outlined

Повний текст джерелаI applied UV resonant Raman spectroscopy (UVRRS) to an ‘in situ’ study of carbon materials at very hight temperature (> 2000 K) or at high pressure (< 1 GPa).The advantages of UVRRS are presented in the first part of this PHD thesis, and used to investigate details of the composition and structure of disordered carbon materials such as: (1) n-type nanocrystalline films, (2) carbonaceous matter in chondrites and (3) tholins, HCN synthetic samples of Titan 's atmosphere.‘In situ’ Raman studies are limited to 2000 K by the visible black-body emission. I designed a high temperature cell to perform UVRRS above this limit. The second part of the manuscript presents Raman spectra of pyrolitic graphite and HOPG up to 2700 K. This data are consistent with anharmonic models up to 900 K, and show the coupling effects of electron-phonon and phonon-phonon. The last one dominates the anharmonicity above 1000 K. The Raman spectra was calibrated as a function of temperature and became a “thermometer” up to 2700 K.For high pressure measurements in the third part, I modified an anvil cell to study by UVRRS, the vibrational changes induced by pressure on very luminescent molecular organic crystals. I present an analysis at 244 nm of resonant Raman modes of perylene crystal under hydrostatic pressure up to 0.8 GPa. Some of them have a non linear feature under pressure, revealing structural and planar modifications of the molecules
