Synthèse et caractérisation de différentes nanoparticules up-conversion à base de fluorures cubiques dopées Yb/Er dans le NIR au VIS

Abstract : The aim of this PhD project is to develop the synthesis of fluoride nanoparticles doped with rare earth or transition metal ions for novel applications in nanophotonics, such as probes for thermal imaging at nanoscale. Nanoparticles can also use for the coating of photovoltaic cells to optimize their yield by absorption of a larger range of wavelengths. The particularity of the fluoride particles doped with the adequate ions, is to exhibit, for example, efficient up-conversion processes or efficient infrared emissions, due to the high ionic nature of the metal-fluorine bonding. Emphasis will be put on the development and optimization of low-temperature millifluidic processes which are able to ensure the chemical, morphology and size homogeneities of the as obtained nanoparticles. The synthesized nanoparticles will be characterized (chemical composition, size distribution, morphology) as well as their physical properties, particularly the luminescence properties. The possibility of a migration of the millifluidic synthesis processes to microfluidic processes should be explored.
