· CaYO2S

CaYO2S is an oxysulfide ceramic compound containing calcium, yttrium, oxygen, and sulfur elements. This material belongs to the rare-earth oxysulfide family and is primarily investigated in research contexts for luminescent and photonic applications due to the optical properties imparted by yttrium incorporation. The material is notable for potential use in phosphors, scintillators, and optical coatings where the combination of oxide and sulfide anion chemistry can provide tunable emission properties and thermal stability advantages over purely sulfide alternatives.

Regulatory Screening

Environmental

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.
