· JVASP-146224· Bi4I3Br

Bi₄I₃Br is a mixed-halide bismuth ceramic compound combining iodide and bromide anions with bismuth cations. This material belongs to the family of halide perovskites and related bismuth compounds, which are actively researched for optoelectronic and photovoltaic applications as lead-free alternatives to conventional semiconductors. The mixed-halide composition offers tunable bandgap and potential advantages in radiation detection, X-ray imaging, and light-emission devices, though it remains largely in the research and development phase rather than established high-volume manufacturing.

Regulatory Screening

Environmental

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.
