| Abstract | A series of zinc tellurite glasses of the composition (90-x) TeO2 10ZnO xBi2O3 by (where x = 10, 15, 20, 25 mol%) weresynthesized using the conventional melt quenching technique at 1,150 C 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 ofBi2O3 in zinc tellurite glasses systems, the physical, optical and luminescence properties of the glasses were investigated. Theresult showed that density increased and molar volume increased with increasing Bi2O3 concentration. The optical absorptionspectra of glasses were measured in the wavelength range of 200 1,100 nm for Bi3+. The intensity of absorption alsoincreased with increasing of Bi2O3 concentration. The intensity of emission bands at 602 nm increased with increasing Bi2O3concentration. In addition. The luminescence properties of Bi3+ -dope TeO2 ZnO Bi2O3 glass system were carried out usingexcitation wavelengths of 302 nm for Bi2O3. It was found that the luminescence peaks around 602 nm. |
