Used in the production of high-performance permanent magnets, such as neodymium-iron-boron (NdFeB) magnets, where dysprosium enhances coercivity and thermal stability, making them suitable for electric motors, hard disk drives, and wind turbine generators.

Employed in the preparation of phosphors for lighting and display technologies, particularly in high-intensity discharge lamps and mercury vapor lamps, contributing to bright white light with excellent color rendering.

Serves as a precursor in the synthesis of dysprosium-containing ceramic materials for nuclear reactor control rods, leveraging dysprosium's high thermal neutron absorption cross-section.

Applied in research for doping into laser crystals and optical materials to improve magnetic and luminescent properties.

Also utilized in the development of catalysts for organic reactions, specialty glasses with high refractive indices and dispersion, solid oxide fuel cells (SOFC), and high-precision temperature sensors.
