· In2 Sb4 Se8 Br2

In₂Sb₄Se₈Br₂ is a mixed-halide chalcogenide semiconductor compound combining indium, antimony, selenium, and bromine in a layered crystal structure. This is a research-phase material within the broader family of halide perovskites and chalcogenide semiconductors, of interest for optoelectronic and photovoltaic applications where bandgap engineering and layer-dependent properties are valuable. The incorporation of bromine as a halide dopant alongside chalcogenide elements offers tunable electronic properties relative to purely selenide or sulfide analogs, making it a candidate for next-generation thin-film photovoltaics, IR detectors, and solid-state lighting where material composition control directly enables performance optimization.

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.
