· Pb0.72Se0.72Sn0.28Te0.28

Pb0.72Se0.72Sn0.28Te0.28 is a quaternary lead chalcogenide semiconductor alloy combining lead selenide, lead telluride, and tin telluride components. This material family is primarily investigated for mid- to long-wavelength infrared (IR) detection and thermal imaging applications, where the narrow bandgap and narrow direct bandgap enable sensitive photodetection in the 3–14 μm spectral region. The alloying of Sn and Te into the Pb-Se-Te system allows fine-tuning of the bandgap and lattice parameters for specific IR wavelengths, making it relevant for defense, medical thermal imaging, and industrial non-destructive testing where competing materials like HgCdTe face manufacturing or cost constraints.

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.
