· Sn0.25Pb0.75Se1

Sn0.25Pb0.75Se is a lead-tin selenide compound semiconductor belonging to the IV-VI narrow-bandgap family, synthesized primarily for infrared optoelectronic applications. This material is notable in thermoelectric and infrared detector research, where the lead-tin composition offers tunable bandgap and carrier properties compared to pure PbSe or SnSe alternatives. The mixed-cation approach enables engineering of thermal and electrical transport for advanced sensing and energy conversion devices, though it remains largely in the research and development phase rather than in high-volume manufacturing.

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.
