La2S3
semiconductor· La2S3
Lanthanum sulfide (La₂S₃) is a rare-earth chalcogenide semiconductor compound combining lanthanum with sulfur, typically studied as a wide-bandgap semiconductor material for optoelectronic and photonic applications. This material is primarily of research and developmental interest rather than established high-volume production, with potential applications in infrared optics, photodetectors, and solid-state lighting where its optical transparency and electronic properties in the visible-to-infrared spectrum are advantageous compared to conventional semiconductors.

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.
