Abstract
Electrical conductivity and dielectric relaxation studies of silver ion-conducting glasses have been prepared using xAg(2)SO(4)-15Ag(2)O-(90-X)(90P(2)O(5)-10MoO(3)) glass system over a temperature range of 298-353 K and frequencies of 10 Hz to 10 MHz. DC conductivities exhibit Arrhenius behavior over the entire temperature range with a single activation barrier. The ac conductivity behavior of these glasses has been analyzed using single power law; conductivity increases linearly in logarithmic scale with Ag2SO4 concentration. The power law exponent (s) decreases, while stretched exponent (beta) is insensitive to increase of temperature. Scaling behavior has also been carried out using the reduced plots of conductivity and frequency, which suggest that ion transport mechanism remains unaffected at all temperatures and compositions.
