· LaScO2S

LaScO₂S is a rare-earth oxysuiflide semiconductor compound combining lanthanum, scandium, oxygen, and sulfur. This material is primarily of research and developmental interest, explored for optoelectronic and photonic applications where the mixed anionic lattice (oxygen and sulfur) can tailor electronic band structure and light-emission properties. While not yet widespread in production, LaScO₂S belongs to an emerging family of rare-earth oxysuiflides being investigated as potential alternatives to conventional semiconductors in phosphors, scintillators, and UV-visible emitting devices due to their tunable optical characteristics.

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.
