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...

| Sumario: | 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 of sodium superoxide doped vanadium phosphate borate glasses. The impedance spectroscopy was employed to investigate transport properties of all glass systems under study. The AC conductivity for all glass systems were investigated in temperature range 308–473 K. The Jonscher's power law found to be fit with conductivity data, which decrease with temperature and satisfies the criteria of the correlated hopping model. The activation energy (Ea) estimated from the Arrhenius plot and it is observed to be 0.12 eV. |
