Abstract
  • Silver iodide-silver molybdate glasses, (AgI)(x)(Ag2MoO4)(1 - x), with x = 0.75 and x = 0.67, exhibit high ionic conductivity, comparable to that of some ionic liquids at room temperature, and low values of the calorimetric glass transition temperature. The behaviour of the attenuation of acoustic waves as a function of temperature in silver iodomolybdate glasses below T-g is peculiar, arising from two different and almost overlapping relaxational contributions. In this work we investigate the frequency dependent conductivity and the dielectric properties of silver iodide-silver molybdate glasses in the mHz-GHz frequency range at temperatures between 300 K and 70 K, aiming in particular to ascertain whether a correlation can be found between the features of the dielectric response and the anomalous mechanical response of these fast ion conducting glasses.
