Dy2Se3 is a dysprosium selenide ceramic compound belonging to the rare-earth chalcogenide family, which combines a lanthanide element with a group XVI semiconductor material. While primarily a research compound rather than a commodity material, dysprosium selenides are investigated for their potential in high-temperature applications, solid-state physics studies, and specialty electronic or photonic devices that exploit rare-earth electronic properties. This material family is notable for exploring thermal stability and electronic behavior in rare-earth systems, though practical engineering applications remain limited compared to more established ceramics.
