Ac conductivity measurements and its analysis has been performed on xBi(2)O(3)-(65-x)Li2O-20ZnO-15B(2)O(3) (0 <= x <= 20) glasses in the temperature range 30-300 degrees C and a frequency range of 100 Hz to 1 MHz. The dc conductivity increased and the activation energy decreased with lithium content. The frequency dependent conductivity has been analyzed employing conductivity and modulus formalisms. The onset of conductivity relaxation shifts towards higher frequencies with temperature. The Almond-West conductivity formalism is used to explain the scaling behavior, and the relaxation mechanism is independent of temperature. (C) 2012 Elsevier Ltd. All rights reserved.
