· Sb2PbSe4

Sb₂PbSe₄ is a ternary semiconductor compound composed of antimony, lead, and selenium, belonging to the family of narrow-bandgap semiconductors with potential for infrared and thermoelectric applications. This material is primarily investigated in research contexts for mid- to long-wavelength infrared detection and sensing, where its narrow bandgap enables response in spectral regions poorly served by conventional semiconductors. It is also explored for thermoelectric energy conversion due to the favorable combination of low thermal conductivity and electronic transport properties typical of heavy-element chalcogenides, positioning it as a candidate alternative to lead telluride in specialized thermal-to-electric applications.

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.
