    • Abstract

       

      The samples of composition 60V2O5–5P2O5–(35−𝑥)B2O3–𝑥CeO2, 𝑥 = 1, 2, 3, 4 and 5 mol% were prepared by the melt-quench method. The prepared samples were characterized by X-ray diffraction, thermogravimetric-differential thermal analysis and impedance spectroscopy. The activation energies were evaluated using glass transition temperature (𝑇g) and peak temperature of crystallization (𝑇c). The dependence of activation energy on composition was discussed. AC conductivity of samples has been analysed. Electrical conductance and capacitance were measured over a frequency range of 20 Hz–1 MHz and a temperature range of 303–473 K. At room temperature, maximum value of electrical conductivity was observed to be 0.0024 S cm−1 for 𝑥 = 1.The samples show semiconducting features predominantly based on an ionic mechanism.
