| Abstract | A new glass system xCdI(2)-(100 - x)[2Ag(2)O-(0.7V(2)O(5)-0.3B(2)O(3))], 5 less than or equal to x less than or equal to 20, has been prepared by melt quenching technique. The electrical conductivity studies of the samples have been carried out at different temperatures and frequencies. The transport number of the Ag+ determined by the emf method is 0.98. The frequency dependence of electrical conductivity has been analyzed by Jonscher's power law. Data were analyzed in terms of permittivity and modulus formalisms. The modulus spectra of the present system suggest a distribution of the relaxation time, which is found to be temperature independent. The cooperative motion due to strong coupling between the mobile Ag+ ions are assumed to give rise to the non-Debye type of relaxation. The behavior of ac conductivity and relaxation phenomenon can be explained by the diffusion controlled relaxation (DCR) model proposed by Elliott. (C) 2004 Elsevier Ltd and Techna Group S.r.l.
