· Pb0.75Sn0.25Se

Pb0.75Sn0.25Se is a lead-tin selenide alloy—a narrow-bandgap IV-VI semiconductor compound that combines lead selenide and tin selenide in a 3:1 ratio. This material is primarily of research and specialized industrial interest for infrared (IR) sensing and detection applications, where its tunable bandgap and strong optical absorption in the infrared region offer advantages over binary parent compounds. The tin alloying modifies the electronic structure relative to pure lead selenide, making it valuable for long-wavelength IR detectors and thermal imaging systems operating in specific spectral windows.

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.
