· YCaO2S

YCaO2S is an oxysulfide ceramic compound combining yttrium, calcium, oxygen, and sulfur elements, belonging to the rare-earth oxysulfide family. This material is primarily of research and development interest for optical and luminescent applications, particularly as a host matrix for phosphors and potential solid-state lighting components. Its mixed anion chemistry (oxygen and sulfide) provides tunable optical properties compared to conventional oxide or sulfide ceramics, making it notable for applications requiring customized emission wavelengths or thermal stability beyond traditional phosphor hosts.

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.
