Impedance spectroscopy study of the AC conductivity of sodium superoxide nanoparticles doped vanadate based glasses

In the present work, we successfully prepared sodium superoxide (NaO2) doped vanadium phosphate borate glasses using normal melt quenching technique of composition 60V2O5–5P2O5–(35-x) B2O3–xNaO2, x = 0, 10, 15 and 20 mol %. The foremost objective of this work is to explore the transport properties...
