Sm2S3

Samarium sulfide (Sm₂S₃) is a rare-earth chalcogenide semiconductor compound belonging to the lanthanide sulfide family. It is primarily investigated in research and emerging technology contexts for optoelectronic and photonic applications where rare-earth dopants and narrow bandgap semiconductors offer advantages in infrared detection, thermal imaging, and luminescent device development. The material remains largely experimental rather than widely commercialized, but represents a promising candidate in the broader field of rare-earth semiconductors where alternatives like PbS or HgCdTe may face toxicity or stability constraints.
