Actually a third year PhD student between the Institute Charles Gerhardt Montpellier (ICGM) and the Institute of Physics of Nice (InPhyNi). Holding a master degree from the University of Rennes 1 in solid state and materials chemistry, and a bachelor in chemistry from the Lebanese University.I use Sol-Gel process to prepare rare earth doped silica nanoparticles and to control their size is the main work during my thesis. I work also on the impregnation of rare earth metals into porous silica and on the preparation of rare earth doped silica monoliths. I finally study their photoluminescence and structural properties.

Abstract

Optical fibers containing rare-earth (RE) doped nanoparticles are investigated to develop new devices such as fiber lasers or amplifiers [1,2]. Thanks to this route, alteration of the spectroscopic properties of RE ions have... [ view full abstract ]
