Consequence of incorporation of transition metals and alkaline earth metal oxides on mixed ionic-electronic conductivity and dielectric characteristics of oxide glasses produced by typical melt quenching with 0.25P2O5–0.35ZnO–xV2O5–(0.4–x)Na2O has been investigated. Some nanophases are identified from the XRD patterns of the glass nanocomposites system. The conduction mechanism of the glass nanocomposite system is explained by Almond-West formalism. The dielectric characteristics have been justified at different frequencies and temperatures. Co-relation between dielectric constant (ε/) and dielectric loss (ε//) concerning the transition metal oxide concentration is established which widens the area of future applicability of the prepared glass composites. The glasses exhibit both electronic and polaronic conductivity, making them particularly suitable for applications in energy storage devices.

摘要

Consequence of incorporation of transition metals and alkaline earth metal oxides on mixed ionic-electronic conductivity and dielectric characteristics of oxide glasses produced by typical melt quenching with 0.25P2O5–0.35ZnO–xV2O5–(0.4–x)Na2O has been investigated. Some nanophases are identified from the XRD patterns of the glass nanocomposites system. The conduction mechanism of the glass nanocomposite system is explained by Almond-West formalism. The dielectric characteristics have been justified at different frequencies and temperatures. Co-relation between dielectric constant (ε/) and dielectric loss (ε//) concerning the transition metal oxide concentration is established which widens the area of future applicability of the prepared glass composites. The glasses exhibit both electronic and polaronic conductivity, making them particularly suitable for applications in energy storage devices.
