Used as a precursor in the production of dysprosium metal and alloys for enhancing the high-temperature performance of neodymium-iron-boron (NdFeB) permanent magnets in electric motors, electric vehicles, and wind turbines.

Employed in research and development of luminescent materials and optical devices due to its strong emission in the visible and near-infrared range.

Utilized in the synthesis of dysprosium-containing complexes for magnetic studies, especially in single-molecule magnet applications.

Serves as a precursor in the preparation of other dysprosium compounds used in nuclear reactor control rods, owing to its high neutron absorption cross-section.

Also used in doping crystals for solid-state lasers, in temperature sensors, and in some specialized catalyst systems for organic transformations.
