Abstract
Abstract AgI: AgPO3 glasses are an interesting model system in which to address the relationships between carrier density and mobility, transport mechanism and medium-range order in fast ion-conducting glasses. In this paper we discuss an anomaly observed in the dc conductivity behaviour below room temperature. This anomaly is related to the opening of percolative channels for AgI contents higher than 30 mol % . Solid-state 109 Ag nuclear magnetic resonance (NMR) measurements on the 1:1 AgI: AgPC3 glass allow us to determine the change in the number of mobile carriers over all the temperature region where the anomaly is observed.
