INVESTIGATION OF ELECTRICAL CONDUCTION IN VANADATE BASED GLASSES

Abstract

The binary glassy systems 60V2O5-(40-x)P2O5 –xB2O3 were prepared by melt quenching technique. The mole of B2O3 was varies from 5 to 20 mol % with constant mol % of V2O5 during preparation of glass samples. The dc electrical conductivity of samples was measured in temperature range 303-473 K and found to be higher for sample 60 V2O5-20P2O5 –20B2O3 . Using the Arrhenius equation of conductivity, the activation energy of conduction is estimated. The conduction in these glasses is takes place by phonon-assisted hopping between the localized states.
