In the present study, the strontium doped vanadium borate glasses were prepared by melt quenching technique. The non-crystalline nature of the samples has been established by the XRD studies. The ac electronic conduction in the temperature form 313 K to 473 K and in the frequency 100 Hz to 5.5 MHz have been studied. The dielectric constant and dielectric loss found to be increased and with increase in frequency they found to be decreased as temperature increases in these glass systems. The high temperature dependent of electronic conduction has been analyzed using Mott’s small polaron hopping model and activation energies were determined. The ac conductivity was observed to quickly fall as soon as the SrO is brought into the glass matrix. Correspondingly, the activation energy is found to increase rapidly. This could be a sign for Sr+ ions may not at all donate to the total ac conductivity and the observed conductivity may be electronic alone which is due to the hopping of electrons between multivalent states of Vanadium ions.
