Abstract
This investigation consists of results of the studies on dielectric properties and a.c. conductivity of Li2O-Ga2O3-SiO2 (LGS) glass with 2.0 mol% of Cr2O3, MoO3, WO3 across 0.01 Hz to 1 MHz and 20 degrees C to 240 degrees C. Structural analysis using optical absorption and IR spectra indicated dopant ions predominantly in Cr3+, Mo6+/Mo5+, W6+ states, and occupied T-d and O-h positions. Dielectric constant and conductivity were found to be the maximal for LGSMo glass, with the lowest impedance, while LGSCr glass exhibited the opposite trend. From the analysis of dipolar relaxation effects probable dipoles were identified in each glass. Studies on conductivity revealed that contribution of ionic components is very low and a substantial polaronic contribution in LGSMo glass, whereas, LGSCr glass showed a larger ionic component, specifically Li+ ion diffusion and hence more useful material for solid-state batteries with respect to the other two glasses.
