· Ba2 Al4 Si6 N8 O8

Ba2Al4Si6N8O8 is an oxynitride ceramic compound combining barium, aluminum, silicon, nitrogen, and oxygen in a single crystalline phase. This material belongs to the rare-earth-free rare-earth-element-free (REE-free) luminescent ceramic family and is primarily investigated for phosphor applications in solid-state lighting, where it serves as a host lattice for rare-earth dopants (typically europium or cerium) to produce efficient photoluminescence. The material is notable for its potential to reduce dependence on critical rare-earth elements while maintaining high luminous efficiency, making it attractive for LED manufacturers seeking sustainable, cost-effective alternatives in a research and early commercialization context.

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.
