· Se1 Pb1

Se₁Pb₁ is a binary semiconductor compound combining selenium and lead in a 1:1 stoichiometric ratio. This material belongs to the IV-VI semiconductor family and is primarily of research interest for its potential in infrared optoelectronic devices, thermoelectric applications, and solid-state physics studies. Lead-selenium compounds are notable for their narrow bandgaps and high charge-carrier mobility, making them candidates for mid- to far-infrared detection and thermal energy conversion, though they remain less commercialized than related lead chalcogenides like PbTe and PbSe used in established infrared detector technology.

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.
