Conductivity relaxation, at 10Hz to 2MHz and 108 to 303K, of fast ion conducting AgI–Ag2O–MoO3 glasses was reported. It was observed that the conductivity relaxation in these glasses was highly non-exponential and that the conductivity relaxation mechanism was independent of temperature but was dependent on composition. It was further observed that the motion of Ag+ ions was decoupled more and more from the viscous motion of the glassy matrix with the increase of AgI content in the composition, giving rise to the increase of the conductivity.
