Electrical Conductivity Enhancement of V2O5-P2O5-Bi2O3 Glasses by Nanocrystallization

Abstract The structural and electrical properties of the x P 2 O 5 -(40 − ) Bi 3 -60V (0 ≤ 20) glass system have been investigated. samples were prepared by conventional melt-quenching technique. X-ray diffraction (XRD) patterns confirmed amorphous nature present glasses. Nanocrystalline grains found due to annealing under study. Nanocrystals with an average grain size 22 nm implanted in structure estimated from XRD glass–ceramic samples. DC conductivity has determined temperature range 300–500 K. It was that general behavior similar for all compositions decrease increasing phosphate content. nanocrystals obtained at crystallization ( T c much higher than initial glass. activation energy (W) enhanced plots temperature-dependent conductivity, be 0.23–0.31 eV glasses 0.19–0.23 nanocrystals.
