· Pb0.75Sn0.25Te

Pb0.75Sn0.25Te is a lead-tin telluride alloy semiconductor belonging to the IV-VI narrow bandgap family, engineered for infrared optoelectronic applications. This material is primarily used in infrared detectors and thermal imaging systems operating in the mid-to-long wavelength range, where its narrow bandgap enables sensitivity to heat radiation at moderate temperatures. The lead-tin ratio is specifically tuned to balance bandgap energy, lattice matching, and thermal stability compared to pure lead telluride or tin telluride, making it valuable for cryogenically-cooled or thermoelectrically-cooled detector arrays in military, scientific, and industrial thermal sensing.

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.
