· Sm2Se3

Sm₂Se₃ is a rare-earth chalcogenide semiconductor compound combining samarium with selenium, belonging to the family of lanthanide selenides studied for optoelectronic and thermoelectric applications. This material is primarily investigated in research settings for infrared optics, solid-state lighting, and thermal energy conversion devices where rare-earth semiconductors offer tunable bandgap and unique optical properties. While not yet widely commercialized compared to mainstream semiconductors, Sm₂Se₃ represents a promising candidate in the rare-earth materials palette for niche high-performance applications requiring mid-infrared transparency or enhanced thermoelectric efficiency.
