Abstract:

Zinc lithium tungsten antimony molybdate glasses containing Lu3+ in (45- x): Mo2O3: 10 ZnO: 10Li2O:10 WO3:25Sb2O3:xLu2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by Xray diffraction studies. The physical parameters like density, dielectric constant and electrical susceptibility have been evaluated. Dielectric constant, refractive index, electronic polarizability varies with increasing mole% of Lu2O3 respectively. The metallization criterion has been calculated on the basis of refractive index and energy gap. It was found to be decreased with increasing refractive index and decreasing energy gap. The large value of metallization criterion indicates that the glass materials are insulators.

Keywords:
