· Pb1Se0.5S0.5

Pb₁Se₀.₅S₀.₅ is a lead-based mixed chalcogenide semiconductor combining lead selenide and lead sulfide in a 1:1 molar ratio. This is a research-stage IV-VI semiconductor material explored for its tunable bandgap and narrow direct bandgap characteristics, positioning it within the established family of lead chalcogenides used in infrared optoelectronics. The partial substitution of selenium with sulfur alters lattice parameters and electronic properties compared to pure lead selenide, making it of interest for engineering applications requiring bandgap engineering in the infrared region.

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.
