Composition dependence of electrical properties of ZnF2-MO-TeO2 glasses

Abstract

Dielectric constant (ε′), loss (tan δ), a.c. conductivity (σ) of ZnF2-MO-TeO2 glasses with varying concentrations of MO (P2O5, As2O3 and Bi2O3) were measured as a function of frequency and temperature over moderately wide ranges. From the analysis of these studies along with IR spectra and DTA results of these glasses, the structural changes in the systems with the concentration of metal oxides are discussed.
