· YAlO2S

YAlO2S is an yttrium aluminum oxysulfide compound belonging to the rare-earth ceramic semiconductor family, combining yttrium, aluminum, oxygen, and sulfur constituents. This material is primarily investigated in research contexts for photoluminescent and scintillation applications, where its crystal structure and rare-earth doping potential enable efficient light emission and detection. YAlO2S and related oxysulfide compounds are notable for their tunability in optical properties and potential use in solid-state lighting, radiation detection, and display technologies where alternatives like traditional phosphors or conventional semiconductors may lack the desired combination of brightness, color purity, and chemical stability.

Export Control

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.
