NdS

Neodymium sulfide (NdS) is an inorganic ceramic compound belonging to the rare-earth chalcogenide family, characterized by ionic bonding between a lanthanide metal and sulfur. While not widely commercialized as a bulk engineering material, NdS and related rare-earth sulfides are primarily explored in research contexts for optoelectronic, photonic, and semiconductor applications where rare-earth doping and tunable electronic properties are advantageous. Engineers would consider NdS-based materials in advanced device development rather than general structural applications, particularly where the unique optical and electronic characteristics of rare-earth compounds provide functional advantages over conventional ceramics.
