Investigation of dielectric relaxation of Molybdenum-Zinc-Selenite glass nanocomposites: temperature and frequency dependency

Abstract

Two bulk glass nanocomposites of xMoO3(1-x) (0.5Se02-0.5ZnO) for $x$ = 0.05, 0.1 and 0.2 compositions have been prepared via slow cooling process of the melt, and the dependency of dielectric properties on temperature and frequency has been studied. The results of the differential scanning calorimetry (DSC) process describes the thermal property of these compositions. The dielectric constant (e/) and the dielectric loss (e//) show an increasing nature with temperature and decrease with frequency. The dynamic conductivity relaxation process is non-Debye type, and the obtained relaxation time shows Arrhenius behavior. The scaled complex electric modulus spectra disclose that the dynamic conductivity relaxation process depends on composition but not depend on temperature.
