Synthesis and different Optical properties of Gd2O3 doped sodium zinc   tellurite glasses
  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.
