· Sm2 S1 O2

Sm₂S₁O₂ is a rare-earth oxysulfide semiconductor compound combining samarium with sulfur and oxygen. This material belongs to the family of mixed-anion rare-earth compounds, which are primarily investigated in research settings for their unique electronic and optical properties arising from the lanthanide 4f electrons. While not yet widely commercialized, oxysulfides of rare earths show promise in photocatalytic applications, luminescent devices, and advanced optoelectronics due to their tunable band structures and strong light-matter interactions.

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.
