YLaO2S
semiconductor· YLaO2S
YLaO2S is an oxysulfide ceramic compound combining yttrium, lanthanum, oxygen, and sulfur, belonging to the rare-earth oxysulfide family of wide-bandgap semiconductors. This material is primarily of research interest for photocatalytic and optoelectronic applications, where its mixed anion chemistry offers tunable electronic properties not easily achieved in conventional oxides or sulfides alone. YLaO2S and related rare-earth oxysulfides are being investigated for visible-light photocatalysis, photoluminescence, and potential wide-bandgap semiconductor devices, though it remains largely in academic development rather than mainstream industrial production.

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.
