· ScYO2S

ScYO2S is a mixed rare-earth oxide-sulfide semiconductor compound combining scandium, yttrium, oxygen, and sulfur in a single-phase material. This is primarily a research-stage compound investigated for its potential in optoelectronic and photonic applications, particularly where the combined oxide-sulfide structure might offer tunable bandgap properties or enhanced light-matter interactions compared to conventional single-phase semiconductors. The material family represents an emerging area in solid-state chemistry where heteroanionic compounds (mixing oxygen and sulfur sites) are explored to overcome limitations of traditional oxides or sulfides in UV–visible or near-infrared device applications.

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.
