Many of the wastes associated with the nuclear fuel cycle are toxic to the biosphere; advancing the use of high resolution spectroscopy applied to these materials will provide the chemical speciation of the interaction between nuclear waste and geological material, improving confidence in a permanent disposal method and informing clean-up operations. Luminescence spectroscopy of uranyl(VI) is a well-established technique for the molecular speciation of uranium-mineral interactions.

In this thesis, the effect of the sample properties on the characteristics of the hot carrier luminescence in graphene is investigated. The present work focuses on the two main issues described below. The first issue is the modification effects of near-infrared pulsed laser excitation on graphene. For excitation fluences several orders of magnitude lower than the optical damage threshold, the interaction with ultrafast laser pulses is found to cause a stable change in the properties of graphene. This photomodification also results in a decrease of the hot photoluminescence intensity. The detai

Abstract:
La recherche scientifique contemporaine en matière de matériaux est largement orientée autour de l’optimisation et l’élaboration de nouveaux matériaux poly-fontionnels, multi-structurés et aux dimensions réduites. De tels matériaux conduisent à s’intéresser à la problématique des comportements spécifiques résultant des différentes interfaces mises en jeu ; il peut s’agir d’interfaces physiques entre différents milieux (états différents, compositions chimiques différentes …) ou des interfaces entre différentes propriétés. Dans ce contexte, nous nous sommes intéressés aux corrélations pouvant ex

Abstract:
Experimental and quantum-chemical investigation of the spectral and luminescent properties of acridine, and its protonated form was performed. The electronic absorption and fluorescence spectra of the acridine were studied at room temperature in ethanolic solutions at different pH values and in other solvents of different chemical nature and polarity.The energies of the excited states, the deactivation rate constants for the excited states, and the dipole moments are presented, which were obtained by calculations using the INDO/S method. Sensor properties of acridine immobilized into SiO2

Abstract:
Sol-gel SiO2 matrices with Polymethine dyes (РМ1, РМ2 and РМ3) were synthesized using citric acid as a catalyst. There were measured the absorption and luminescence spectra of РМ1, РМ2 and РМ3 dyes (with a concentration of 1·10–5 mole/dm3) in different solvents (ethanol, dimethylformamide, formamide and water) and in sol-gel SiO2 matrices. The said dyes were found to be present in monomeric form in ethanol, dimethylformamide and formamide. PM1 dye did not form dimers in water and in matrices and retained its color. PM2 and PM3 dyes aggregated into the network of SiO2 matrices and in water

Abstract:
Quantum dots are a part of very important our technological future because of their intriguing and useful properties. These properties are different in character from those of the corresponding bulk material. Quantum dots are inorganic artificial semiconductor nanocrystal whose electrons influence their physical and chemical properties. Zinc oxide quantum dots were synthesized through an ethanol based precipitation via colloidal synthesis method at various pH values. Various emission colors were obtained because the excited quantum dots of various sizes emitted specific wavelengths of light. T
