The effect of point defects on the ionic conductivity of RbAg4I5solid electrolytes

The effect has been studied of additive coloring on the magnitude of ion conductivity of RbAg4I5 crystals. It has been found that slight changes of silver stoichiometry of 10−3 at.% can lead to considerable variations of the ionic conductivity Δ[sgrave]i/[sgrave]i ≃ 0.1. The dependence has been observed of the magnitude of ion conductivity on the ratio between the integral intensities of the main bands in the photoluminescence spectrum of the γ-phase of RbAg4I5 which associated with the luminescence centres containing vacancies and interstitials of silver cations.
