· JVASP-45309· NaErP2S6

NaErP2S6 is a rare-earth phosphide sulfide ceramic compound containing sodium, erbium, phosphorus, and sulfur. This material belongs to the family of mixed-anion ceramics and appears to be primarily a research-phase compound rather than an established industrial material. Rare-earth phosphide-sulfides are of interest for potential applications in photonics, thermal management, and specialized electronic devices where the unique crystal structure and rare-earth dopant properties could provide optical or thermal functionality distinct from conventional oxide ceramics.
