Used in the production of dysprosium-containing phosphors for high-intensity discharge lamps and color television tubes due to its strong luminescent properties under UV excitation. Serves as a precursor in the synthesis of dysprosium oxide and other dysprosium-based materials used in magnetic storage devices and rare-earth magnets. Employed in research for doping in solid-state lasers and optical materials. Also utilized in catalyst preparation for organic reactions and in the development of ceramic capacitors and sensors requiring rare earth elements.
