· Sr4 Se4 O16

Sr₄Se₄O₁₆ is an oxychalcogenide semiconductor compound combining strontium, selenium, and oxygen into a mixed-anion crystal structure. This is a research-phase material studied for its potential in solid-state ionic conductors, photocatalysis, and optoelectronic devices; it represents an emerging class of layered semiconductors where oxygen and chalcogen anions can create tunable bandgaps and ion transport pathways not found in conventional binary semiconductors.

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.
