· JVASP-117858· PbBr

Lead bromide (PbBr) is an ionic ceramic compound belonging to the halide perovskite family, characterized by a lead cation bonded to bromide anions in a crystalline structure. This material is primarily investigated in research contexts for optoelectronic and photonic applications, particularly as a component in perovskite solar cells, radiation detectors, and X-ray imaging devices where its bandgap and charge-carrier properties are exploited. Engineers consider lead bromide-based compositions when seeking high atomic-number materials for radiation shielding or detection, though practical deployment remains limited by toxicity concerns, moisture sensitivity, and ongoing optimization of stability compared to more robust alternatives like lead iodide or tin-based perovskites.

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.
