Abstract: Abstract: Dielectric constant (ε′), loss (tan δ), a.c. conductivity (σ) of ZnF<subscript>2</subscript>-MO-TeO<subscript>2</subscript> glasses with varying concentrations of MO (P<subscript>2</subscript>O<subscript>5</subscript>, As<subscript>2</subscript>O<subscript>3</subscript> and Bi<subscript>2</subscript>O<subscript>3</subscript>) 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.
