Abstract: | Phase diagram of Cu7GeS5I-Cu7GeSe5I superionic system was investigated by the differential thermal analysis (DTA). Chemical interaction in Cu7GeS5I-Cu7GeSe5I system was studied by X-ray phase analysis (XPA), microstructural analysis, and density determination. Compositional behaviour of diffuse reflection spectra and energy gap due to S→Se anion substitution in Cu7Ge(S1−xSex)5I solid solutions are discussed. |
