What is Dysprosium Oxide used for?

Dy2O3 (dysprosium oxide) is used in ceramics, glass, phosphors, lasers and dysprosium halide lamps. Dy2O3 is commonly used as an additive in making optical materials, catalysis, magneto-optical recording materials, materials with large magnetostriction, measurement of neutron energy-spectrum, nuclear reaction control rods, neutron absorbents, glass additives, and rare earth permanent magnets. It is also used as a dopant in fluorescent, optical and laser-based devices, dielectric multilayer ceramic capacitors (MLCC), high efficiency phosphors, and catalysis. The paramagnetic nature of Dy2O3 is also utilized in magnetic resonance (MR) and optical imaging agents. In addition to these applications, dysprosium oxide nanoparticles have recently been considered for biomedical applications such as cancer research, new drug screening, and drug delivery.
