· LaYO2S

LaYO2S is a rare-earth oxysulfide semiconductor compound combining lanthanum, yttrium, oxygen, and sulfur in a mixed-anion crystal structure. This material belongs to the family of lanthanide oxysulfides, which are primarily of research and developmental interest for optoelectronic and photonic applications where the combination of rare-earth luminescence with semiconducting properties is advantageous. LaYO2S and related oxysulfides are explored for phosphor materials, scintillators, and potential wide-bandgap semiconductor devices where traditional oxides or sulfides alone are insufficient.

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.
