· JVASP-123810· Bi5I

Bi₅I is an iodide ceramic compound in the bismuth halide family, representing a mixed-valence bismuth iodide phase. This material is primarily of research interest for optoelectronic and photovoltaic applications, where bismuth halides are being explored as lead-free alternatives to conventional perovskite absorbers due to their tunable bandgap and potential for stable, non-toxic solar cells and radiation detection devices.

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.
