Abstract

The ionic conductivity of the 0.5 AgI.xSbI₃.(0.5-x)Sb₂S₃ and 0.5 AgI.xPbI₂.(0.5-x)Sb₂S₃ glassy systems with a constant silver concentration has been investigated. It was found that the Ag⁺ ion transport is closely related to the heavy metal iodide content. The conductivity activation energy decreases from 0.38 to 0.28 eV, and the room temperature conductivity increases by a factor of 100 with increasing x. A structural model based on available neutron diffraction, EXAFS and ¹²⁹I-Mössbauer spectroscopy data was proposed to explain the observed phenomena.
