Transport And Relaxation Study Of Ionic Phosphate Glasses

Dynamic processes in glassy materials with ionic conductivity are extremely important since the ion transport significantly affects their practical performance. Conductivity measurement and dielectric relaxation spectroscopy are powerful techniques that reflect the essential features of the transport and relaxational dynamics of the mobile ions that encounter different kinds of site and ionic hopping motion connected with charge mobility. Acoustic spectroscopy is another technique for the study of relaxations in glasses. In this paper, the acoustic and electrical relaxation processes are compared on identical phosphate glasses of the systems CuI-CuBr-Cu2O-P2O5 and CuI-CuBr-Cu2O-P2O5-MoO3.
