· Dy2 Se2

Dy₂Se₂ is a rare-earth selenide semiconductor compound combining dysprosium (a lanthanide element) with selenium. This material belongs to the rare-earth chalcogenide family and is primarily of research and emerging-technology interest rather than established industrial production. The compound is investigated for potential applications in optoelectronics, thermal management in high-temperature devices, and as a component in advanced functional materials where rare-earth elements provide unique electronic and magnetic properties.
