Abstract

The doctoral work will address the sinthesis of glass and glass-ceramic materials of Pbx.A1-xO.SiO2, with A-Ni,Co,Cr, with low and high dopant levels, to study the structural characteristics by Raman scattering and optical properties by optical absorption and photoluminescence under high hydrostatic pressure conditions.
