Abstract
The aim of this project is to investigate the influence of hydroxyl (OH) content in the excited states lifetime and emission quantum efficiency of fluorescence in Nd3+ doped TeO2-WO3 and Er3+/Yb3+ co-doped TeO2-Li2O-TiO2 glass systems. Samples will be melted in an electric furnace with atmosphere control. The structural study of the glasses will be done by the infrared, Raman, and X-ray d…
