· Pb0.85Sn0.15Te

Pb0.85Sn0.15Te is a lead-tin telluride alloy, a narrow-bandgap semiconductor belonging to the IV-VI compound family commonly studied for infrared and thermoelectric applications. This material is primarily investigated for mid-infrared radiation detection and thermal-to-electric energy conversion, where its tunable bandgap and carrier mobility make it competitive with competing infrared detector materials. Lead telluride-based alloys are well-established in research and specialized industrial contexts, valued for their sensitivity in the 3–5 μm infrared window and solid-state cooling potential, though deployment remains more limited than mainstream semiconductors due to toxicity constraints and processing complexity.

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.
