dc.description.abstractThe dielectric properties in two series of single and mixed alkali doped vanadotellurite glasses have been investigated in the frequency range 50 Hz to 5 MHz and temperature range 300 K to 500 K. Hunt's model was invoked to analyze the data and the results indicated that the relaxation process has a local character which can be described by hopping between pairs of multivalent sites. Activation energies for dielectric loss process were found to be in close agreement with dc activation energies. The linear relationship between ac and dc conductivities has been confirmed in both systems.en_US
