· Sn0.15Te0.15Pb0.85Se0.85

Sn0.15Te0.15Pb0.85Se0.85 is a quaternary lead-tin telluride-selenide compound belonging to the IV-VI narrow bandgap semiconductor family, typically studied for thermoelectric and infrared detector applications. This material represents a research-phase composition engineered to optimize the bandgap and carrier transport properties intermediate between lead selenide (PbSe) and lead telluride (PbTe) end-members. The tin and tellurium additions modify the electronic structure and thermal properties compared to binary lead chalcogenides, making it of interest for specialized sensing and energy conversion devices where mid-infrared responsivity and thermal stability are critical.

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.
