Sharp changes in the characteristics of the luminescence band with a photon energy of 2 eV have been observed in the γ phase of the superionic conductor RbCu4Cl3I2 at 60 K. It is suggested that the observed anomaly results from a change in the structure of the ion subsystem near the charged center which is responsible for the radiative recombination.
