Abstract

The oxide glasses with composition xV2O5-(40-x) Bi2O3-60B2O3; (0≤x≤22.5) were prepared by rapid melt quench technique. The structural investigation of these glasses was performed by monitoring the infrared transmission spectra. It was found that the glass system under study consist of randomly connected BO3 & BO4 structural units. The density and molar volume of glasses were found to depend on V2O5 content. The conduction mechanism in these glasses was discussed in terms of small polaron hopping (SPH) theory proposed by Mott. It was observed that at 400 K, the dc conductivity increases with increasing vanadium content and ranging from 2.31×10-10 (Ωm)-1 to 9.97×10-6 (Ωm)-1..
