Abstract
- A set of vanado-zinc-boro-phosphate glass nano composites of composition, (B2O3)0.2-(P2O5)0.5-x-(ZnO)0.1-(V2O5)0.2-(Li2O)x; x=0 to 0.4 have been made by melt quenching method. XRD results confirmed phase formation. Density and molar volume varied arbitrarily with Li2O content indicating drastic structural changes occurring in the samples with Li2O concentration. Changes in dc conductivity with temperature has been analyzed using Mott’s small polaron hopping and variable range hopping models. Activation energy for conduction and density of states at Fermi level have been determined. Observed variations in conductivity and activation energy with Li2O concentration have been attributed to interplay between the polaronic and ionic conductions. Various polaron related parameters have also been determined. [ABSTRACT FROM AUTHOR]
