A new kind of ion-conducting glasses based on GeS2-Ga2S3-AgI system is prepared. A relatively large amount of silver can be dissolved into this kind of glass system, and the obtained glasses are still transparent in the red part of the visible spectrum. Only a three times increase in the silver concentration can lead to approximately two hundred times increase in the ionic conductivity. The structural contributions to the ionic conductivity of the glasses are discussed. The present glasses show potential to be used as solid state electrolyte.

Our newest result has shown that the conductivity as high as 10−5 Scm−1 can be achieved for the [(GeS2)40-(Ga2S3)30-(AgI)30]80-Ag20 sample which contains 15.5 at. % Ag.
