· Pb0.75Ge0.25Te

Pb₀.₇₅Ge₀.₂₅Te is a lead-germanium-telluride compound semiconductor belonging to the IV-VI narrow-bandgap material family, engineered for infrared detection and thermal imaging applications. This alloy composition is primarily used in thermoelectric coolers and infrared detector arrays operating in the mid-wave infrared (MWIR) and long-wave infrared (LWIR) regions, where it offers advantages over binary PbTe in terms of bandgap tunability and thermal stability. The material is notable in military and scientific imaging systems where high sensitivity and temperature-dependent performance control are critical, though it remains less common than established alternatives like HgCdTe due to processing complexity and material availability 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.
