Conductivity measurements and modulus formalism have been used to study the transport properties of PbI2 doped silver boro-vanadate glasses prepared by melt quenching technique. The samples are characterized by XRD and DSC measurements. A correlation between R-T, the decoupling index and sigma(DC) has been discussed. The observed conductivity values suggest enhancement in conductivity by the introduction of PbI2 salt in the host glass matrix. AC conductivity data are analyzed by fitting the data to Jonscher's universal power law, sigma'(omega) = sigma(DC) + A omega(n). The power law exponent, n, is found to be independent of temperature and composition. The experimental modulus spectra are analyzed and calculated the stretched exponential constant l using the non-linear KWW decay function. Furthermore, the scaling of both ac conductivity and electric modulus at different temperatures is found to merge near perfectly on to a single master curve suggesting that all the dynamic processes possess good time temperature superposition.
