Abstract

Europium oxide doped boro tellurite glasses of different compositions have been synthesized by using melt quenching procedure. The synthesized glasses contain a composition of (70-x) B2O3-15TeO2 -10Na2O-5PbO-xEu2O3 with x = 0, 0.1, 0.3, and 0.4 mol%. Raman spectroscopic investigations on prepared glasses have been carried out to study the structures and vibrations of atoms in the glass network. By Raman spectra, it is clear that the prepared glass samples are possessing the boroxol rings and also found the different vibrations in Te-O-Te bonds. The emission spectra were done by spectrofluorometer techniques to investigate the luminescent properties of these glasses with excitation wavelength as 394 nm and emission wavelength as 612 nm.
