application

Dysprosium is used along with vanadium and other elements to make laser materials and commercial lighting. Nickel oxide-nickel cermets are used in neutron-absorbing control rods in nuclear reactors because of their high thermal neutron absorption cross section.

Dysprosium is used in dosimeters to measure ionizing radiation.

Iodination and bromide are used in high-intensity metal halide lamps. These compounds dissociate near the hot center of the lamp, releasing isolated atoms.

Several paramagnetic crystalline salts of para (Dy gallium garnet, DGG; Dy aluminum garnet, DAG; Dy iron garnet, DyIG) are used in adiabatic demagnetization refrigerators.
