        My research focused on the synthesis of nanoparticles (TiO2, Y2O3, Y2O3/TiO2) doped rareearth elements (Er and Yb) by the sol–gel method under supercritical drying conditions of ethanol for photovoltaic application and the preparation of suspensions of elaborated nanoparticles in different solvents (water, ethanol, methanol, and butanol) by a two-step powder dispersion process using several ultrasonication methods.

 

The morphological, structural, thermal, spectroscopic and luminescence properties of these nanopowders have been studied. The aim of the suspension was to prepare a stable suspension for a certain time period and then to produce doped and undoped nanoparticle coatings for photovoltaic application. The effects of dopants and solvents on the dispersibility and stability of powders suspensions were evaluated.
