· Au4 Bi4 Br24

Au₄Bi₄Br₂₄ is a mixed-halide perovskite semiconductor compound containing gold, bismuth, and bromine—a member of the emerging halide perovskite family that has attracted significant research attention for optoelectronic applications. This is an experimental/research material rather than an established commercial product; compounds in this family are being investigated for their tunable bandgaps, potential photoluminescence, and semiconducting behavior, though stability and scalability remain active research challenges. Researchers select gold-bismuth halide perovskites over more conventional semiconductors when exploring novel light-emitting devices, radiation detection, or photovoltaic prototypes where the unique electronic structure and compositional flexibility of halide perovskites offer advantages.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
