We investigate the DC transport properties of 60V₂O₅–5P₂O₅–(35-x)B₂O₃–xDy₂O₃ (x = 0.4, 0.6, 0.8, 1.0 and 1.2 mol%) glasses as function of temperature which were prepared using the conventional melt-quenching method. These glasses are characterised by thermo gravimetric-differential thermal analysis (TG-DTA). Activation energy (E_DC) is obtained from Arrhenius plots of temperature-dependent DC conductivity, and it is found to be 0.30 eV for high conducting glass. In order to understand the role of Dy₂O₃ in these glasses, the density and molar volume are investigated. The results show that molar volume of the glass increases with the increasing of Dy₂O₃ concentration. The ionic conductivity is found to be dominant over the electronic conductivity and varies between 82% and 96%.
