Abstract
Relaxation dynamics of Ag+ ions and scaling of the conductivity spectra in lead bismuthate glasses of different compositions have been investigated in the frequency range from 10 Hz to 2 MHz and in the temperature range from 83 K to just below glass transition temperature. We have observed that relaxation dynamics and the frequency exponent depend on the cation constriction. We have also observed that the scaling of the conductivity spectra obeys time-temperature superposition principle, but it is dependent on composition.
