· Ce2 Se1 O2

Ce₂SeO₂ is an oxychalcogenide semiconductor compound combining cerium, selenium, and oxygen. This is a research-phase material within the broader family of rare-earth oxychalcogenides, which are being investigated for optoelectronic and photocatalytic applications where the mixed anion chemistry can tune bandgaps and carrier properties. Interest in this material class stems from potential advantages in photovoltaics, photodetectors, and environmental remediation applications where conventional semiconductors fall short.

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.
