metal· JVASP-107402· K2BiAuBr6
K2BiAuBr6 is a mixed-metal halide compound containing potassium, bismuth, gold, and bromine—a member of the double-perovskite family of materials. This is a research-phase compound being investigated for optoelectronic and photovoltaic applications, where the combination of heavy metals (bismuth and gold) provides favorable electronic and optical properties while the halide framework enables tunable band gaps. While not yet commercially established, compounds in this material class are notable for potentially offering lead-free alternatives to conventional perovskites with enhanced stability and reduced toxicity concerns.
