· Dy2 S1 O2

Dy2S1O2 is an oxysulfide semiconductor compound combining dysprosium with sulfur and oxygen, representing a rare-earth mixed-anion material family of significant interest in materials research. This compound belongs to the broader class of rare-earth chalcogenides and oxychalcogenides, which are being actively investigated for optoelectronic and photonic applications due to their tunable bandgaps and unique electronic properties derived from rare-earth elements. While primarily in the research and development phase rather than mainstream industrial production, Dy2S1O2 and similar rare-earth oxysulfides show promise in photocatalysis, thin-film electronics, and specialized optical devices where the combination of rare-earth magnetism and semiconductor behavior can be engineered.

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.
