Abstract

This project is to study the effect and role of ZnO on structural properties of ternary (90-jc)TeO2-10Nb2O5-(x,)ZnO glass system by using Fourier Transform Infrared (FTIR) spectroscopy. Ternary (90-x)TeO2-10Nb2O5-(x)ZnO; x = 0-15 mol% were prepared by melt-quenching method. X-ray powder diffraction (XRD) result confirmed that all the samples are amorphous. Infrared absorption spectrum shows formation of Zn04 tetrahedral and Te03 trigonal pyramid (tp) which indicate formation of both bridging oxygen (BO) and non-bridging oxygen (NBO) ions. The glass transition temperature, Tg increased from 364.04 °C to 381.21 °C with the increased in the concentration of ZnO to the glass system.
