Yb1 Bi2 Br1 O4
semiconductor· Yb1 Bi2 Br1 O4
Yb₁Bi₂Br₁O₄ is an ytterbium-bismuth bromide oxide semiconductor, a mixed-halide perovskite-related compound currently in research development rather than established production. This material belongs to the emerging class of halide semiconductors being investigated for optoelectronic and photovoltaic applications, where the combination of rare-earth (ytterbium) and bismuth elements offers tunable band gaps and potential stability advantages over lead-based alternatives. The bromide-oxide hybrid structure distinguishes it from conventional semiconductors and makes it a candidate for next-generation light-emitting, photovoltaic, or radiation-detection devices where lead-free compositions are prioritized.

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.
