Abstract: A series of Semiconducting borate glass samples doped with vanadium in the composition range (H3BO3)1 + (V2O5)1-x where x ranging from 0.1, to 0.5 has been prepared by melt quench technique. The samples were annealed and their non-crystalline nature was confirmed by X-ray diffraction studies. Archimedes principle was adopted to measure room temperature density of the glass samples. High and low temperature DC electrical conductivity of the samples were analyzed and various polaron related parameters were investigated in the light of Mott’s SPH for T > 
and Mott’s VRH and Greaves VRH for T < (where 
Debye’s temperature). The investigations in these glass systems showed to be non-adiabatic electrical conduction. As per as above theories, the calculated activation energies, conductivities and various polaron parameters were discussed. The detailed results of all the above parameters were discussed and it is for the first time the pure borate glasses doped with vanadium ions subjected to dc electrical conduction mechanism within the studied composition range.
Keywords: oxide glasses, single TM ion, high and low temperature, transport properties.
