· BiBr3

Bismuth tribromide (BiBr3) is a layered halide semiconductor compound that belongs to the family of metal halides with potential optoelectronic and photonic applications. This material is primarily investigated in research and early-stage development contexts for next-generation optoelectronic devices, particularly where its layered crystal structure and semiconducting properties can be exploited. BiBr3 is notable as a lead-free alternative in halide perovskite research, addressing toxicity concerns in emerging photovoltaic and light-emission technologies, though it has not yet achieved widespread commercial adoption compared to other halide platforms.
