· Pb4 Se1 Br6

Pb₄Se₁Br₆ is a mixed-halide lead chalcogenide semiconductor compound combining lead, selenium, and bromine in a layered perovskite-like structure. This is primarily a research material being investigated for optoelectronic applications, particularly in the context of lead-halide perovskite alternatives and solid-state radiation detection; the selenium substitution and bromine incorporation are being explored to engineer bandgap, stability, and carrier transport properties relative to more-studied lead-iodide perovskites.

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.
