· JVASP-85135· NaEuS2

NaEuS₂ is an inorganic ceramic compound containing sodium, europium, and sulfur—a rare-earth sulfide ceramic with potential applications in specialized optical and electronic materials. This is a research-stage material primarily investigated for its luminescent properties leveraging europium's characteristic photoemission behavior, rather than a widely commercialized engineering ceramic. The material family is of interest to researchers exploring rare-earth ceramics for next-generation lighting, display phosphors, and sensing devices where europium's strong visible-light emission offers advantages over conventional alternatives.
