Electrical characterization and dielectric behavior of PbO·Bi2O3·Ga2O3 glasses

Abstract

In the present work, PbO·Bi2O3·Ga2O3 glasses were synthesized using standard melt-quench technique. The temperature dependent conductivity data of the glasses have been obtained using impedance spectroscopy in the frequency range from 10Hz to 7MHz and in the temperature range from 473K to 703 K. Complex Impedance plots suggest the non-Debye nature of relaxing ions. The dc conductivity follows Arrhenius behavior and decreased with increase in PbO content because of increase of network forming PbO4 units, increases the network dimensionality and blocking the migration of mobile ions.
