· JVASP-101486· K2RbAuBr6

K2RbAuBr6 is a mixed-halide double perovskite compound containing potassium, rubidium, gold, and bromine elements. This is a research-phase material being investigated primarily for optoelectronic and photovoltaic applications, particularly as an alternative to lead-based perovskites for solar cells and light-emitting devices. The compound's mixed-cation architecture and gold coordination chemistry make it notable for exploring lead-free perovskite systems with potentially improved stability and tunable electronic properties compared to conventional organic-inorganic halides.
