Pb1 Se1
semiconductor· Pb1 Se1
Lead selenide (PbSe) is a narrow-bandgap semiconductor compound from the IV-VI material family, typically used in infrared detection and thermoelectric applications. This material is valued in thermal imaging systems, infrared sensors, and mid-wave to long-wave infrared photodetectors where its direct bandgap and high carrier mobility enable sensitive detection at room temperature or with modest cooling. Engineers select PbSe over alternatives like HgCdTe or InSb when cost-effectiveness, manufacturability, and performance in the 3–5 μm infrared window are balanced priorities, though it remains less common in high-volume consumer applications compared to cooled detectors in scientific and military markets.

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.
