Abstract
Ternary tellurite based glasses [(TeO2)0.7 (B2O3)0.3]1-x (Bi2O3)x was prepared by melt quenching method with suitable melting and quenching temperature. A series of glasses were selected from 0.05 to 0.30 mol % and its glass-forming region was determined. The density, molar volume and refractive index increase when bismuth ions Bi3+ increase, this is due to the increased polarization of the ions Bi3+ and the enhanced formation of non-bridging oxygen (NBO). The values of optical band gap, Eopt decreases when Bi2O3 content increases. Urbach energy for each composition was also calculated and was found to be dependent on the glass composition.
