Abstract
Bismuth based glasses containing ZnO, B2O3 and Li2O are investigated by different physical, spectroscopic and transport techniques. Raman and IR studies reveal that these glasses are built up of [BiO3] and [BiO6] units. Zinc in tetrahedral form is also observed. Glass transition temperature varied nonlinearly with the composition. Also the variation in conductivity with composition is very small and non-linear. The nonlinear behaviour in these properties is attributed to mixed former effect. Molar polarizability is also estimated from optical and dielectric properties. The polarizability values show dependence on Bi2O3 content and varied nonlinearly.
