· PbSnS3

PbSnS3 is a mixed-metal sulfide semiconductor compound containing lead, tin, and sulfur, belonging to the family of narrow-bandgap semiconductors and chalcogenides. This material exists primarily in research and development contexts, where it is being investigated for infrared optoelectronic applications, thermoelectric devices, and potentially photovoltaic systems that exploit its unique electronic structure. Compared to traditional wide-bandgap semiconductors, PbSnS3 and related lead-tin chalcogenides offer the possibility of efficient operation in the mid-to-far infrared spectrum, making them candidates for thermal imaging, infrared detectors, and waste-heat recovery technologies, though the material remains largely in experimental stages with limited commercial deployment.

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.
