Role of free volume in governing electrical transport in V2O5–Cu2O–P2O5 glass ceramic nanocomposites

Abstract Glass–ceramic nanocomposites of xV₂O₅–(40−x)Cu₂O–60P₂O₅ (x = 10–40 mol%) were prepared by melt quenching followed by heat treatment at 873 K. XRD analysis confirmed the formation of Cu₂O and V₂O₅ nanocrystalline phases with crystallite sizes in the range of 16–27 nm embe...
