  Optical properties of a series of Gd2O3 doped sodium zinc tellurite
[xGd2O3-(0.8-x) TeO2-0.1Na2O-0.1ZnO] glasses prepared by conventional melt
quenching method have been studied. UV-Vis spectrophotometer was used in the
integrating sphere mode at room temperature to study the effect of Gd2O3 doping
on the optical band gap, refractive index, dielectric constant and
susceptibility within the wavelength range from 230-800 nm. Density is measured
using Archimedes principle for the calculation of molar volume, molar
refraction, polarizability and metallization criterion of the glasses.
