Ionic relaxation in AgI-Ag2O-TeO2 glasses
Description
We report the ionic conductivity relaxation in fast ion conducting glasses in the system xAgI-(1- x)(0.40Ag2O-0.60TeO2) in the temperature range 128-303 K and in the frequency range 10 Hz-2 MHz. We have observed that the conductivity relaxation can be described by the highly non-exponential Kohlrausch-Williams-Watts function. The Ag+ ions have to overcome the same barrier while relaxing as well as while conducting. We have further observed that the migration of Ag+ ions in the glassy matrix is highly cooperative and the cooperation is extended as the AgI content is increased
