· SrTaO2N

SrTaO₂N is an oxynitride perovskite semiconductor combining strontium, tantalum, oxygen, and nitrogen in a mixed-anion crystal structure. This is primarily a research material investigated for visible-light photocatalysis and solar energy conversion applications, where the nitrogen substitution narrows the bandgap compared to oxide analogues, enabling activation under sunlight rather than UV alone. Its development represents the broader strategy of engineering perovskite semiconductors with tunable optoelectronic properties for renewable energy and environmental remediation, though industrial adoption remains limited outside specialized photocatalytic systems.

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.
