The composite solid electrolyte systems, (1-x)Pb(NO3)2:xCeO2 (x= 0, 0.02, 0.03, 0.04, 0.05 and 0.08), have been investigated by XRD for structural properties, SEM with EDS for morphological studies and Electrical properties through impedance spectroscopy. The frequency and temperature dependence of ac conductivity, dielectric constant and dielectric loss were measured between the temperatures 30oC to 340oC in the frequency range 1Hz to 10MHz. The complex impedance data is analyzed in conductivity, permittivity and electric modulus formalism in order to through light on transport mechanism. Variation of ac conductivity against frequency suggests the response obeying universal power law. The dynamics of conducting ion is studied through Jonscher’s Universal power law. The parameters of n and A of Jonscher’s Universal law suggest these values are strongly temperature sensitive. The variation of dielectric permittivity, loss, and modulus spectra were found to be consistent with conductivity. Impedance, dielectric and modulus analysis had indicated the non-Debye behavior in these composites. The relaxation phenomena were observed in all formalisms. Copyright © 2017 VBRI Press.
