The measured conductivity data of these glasses are analyzed using Cole-Cole type impedance response function, Jonscher's universal power law and Dyre's random free energy barrier model. To get a consistent stand point on ion dynamics, different microscopic models and theories proposed for the ion conduction mechanism in disordered ionic solids are discussed and compared. Universality features of ac conductivity and its scaling behavior are discussed. The compositional dependence scaling behavior in borate and bismuthate glasses are studied using Jonscher's power law hopping frequency ωp and minimum jump frequency γmin in Dyre's random free energy barrier model. The scaling results are compared and reported.
