Abstract

A series of zinc tellurite glasses of the composition (90-x) TeO2 – 10ZnO – xBi2O3 by (where x = 10, 15, 20, 25 mol%) were synthesized using the conventional melt quenching technique at 1,150 oC for 1 hours 30 minutes. This research the physical, optical and luminescence properties of the glasses by the process just described produced. In order to understand the role of Bi2O3 in zinc tellurite glasses systems, the physical, optical and luminescence properties of the glasses were investigated. The result showed that density increased and molar volume increased with increasing Bi2O3 concentration. The optical absorption spectra of glasses were measured in the wavelength range of 200 – 1,100 nm for Bi3+. The intensity of absorption also increased with increasing of Bi2O3 concentration. The intensity of emission bands at 602 nm increased with increasing Bi2O3 concentration. In addition. The luminescence properties of Bi3+ -dope TeO2 – ZnO – Bi2O3 glass system were carried out using excitation wavelengths of 302 nm for Bi2O3. It was found that the luminescence peaks around 602 nm.
