· JVASP-19845· DySe

Dysprosium selenide (DySe) is an inorganic ceramic compound belonging to the rare-earth chalcogenide family, formed by combining dysprosium (a lanthanide) with selenium. While primarily explored in research and materials science contexts, DySe is investigated for applications requiring high-temperature stability, semiconductor properties, or specialized optical characteristics typical of rare-earth compounds. Its selection is driven by the unique electronic and thermal properties dysprosium imparts, making it relevant for niche advanced applications where conventional ceramics or semiconductors fall short.
