摘要：

The silver borophosphate glass system has been investigated using AgI as an additive halide. Electrochemical properties of the prepared glass electrolyte system x.AgI:(100-x).[(30Ag(2)O:(56B(2)O(3)-14P(2)O(5)))] has been prepared using conventional melt quenching technique. Structural characterization has been employed using XRD diffraction pattern to confirm the amorphous nature of the samples, FT-IR analysis is carried out to study the nature of the chemical bonding and different vibrational modes of structural units present in the composition. The glass transition (T-g) has been measured using TG/DTA technique. Electrical conductivity measurements have been carried out in the temperature range from 303 K to 373 K using complex impedance spectroscopy (CIS). The modulus formalisms along with stretching parameter (beta) and decoupling index (R-tau) are calculated. The conductivity and modulus scaling of the prepared system using different models are studied. The present paper discusses the conduction mechanism and physical parameters of conductivity.
