摘要：

Solid solutions Of Cu7SiS5I-Cu7GeS5I System Were synthesized using solid-phase reactions involving a technique specifically developed for the synthesis of ternary compounds that exhibit incongruent melting behaviour. Chemical interaction in the Cu7GeS5I-Cu7SiS5I system was studied by X-ray phase analysis, microstructural analysis and density determination. Specific features of the energy gap and its compositional behaviour with Si -> Ge cation substitution in Cu7SiS5I-Cu7GeS5I solid solution system are reported. (c) 2007 Elsevier B.V.
