· JVASP-37159· NaSmS2

NaSmS2 is a rare-earth sulfide ceramic compound containing sodium and samarium. This material belongs to the family of lanthanide chalcogenides, which are primarily investigated for their electronic and photonic properties rather than structural applications. While not widely commercialized, sodium samarium sulfides are of research interest for potential use in optical devices, solid-state lighting, and semiconductor applications where rare-earth dopants provide unique luminescent or electronic characteristics.
