An investigation was made of the conductivity spectra, at various temperatures, for the model glasses (AgI)x(AgPO3)1–x, with x = 0 to 0.6 and the numbers of mobile Ag+ ions contributing to the transport process were estimated. It was shown that a fraction of the total number of Ag+ ions contributed to the transport process. It was further observed that the fraction of Ag+ ions which contributed to the transport process was independent of the temperature as well as of the AgI content. The mobility of Ag+ ions increased, leading to an enhancement of the conductivity due to AgI doping. The results revealed the role played by AgI in ionic transport in fast ion conducting glasses.
