Dysprosium Oxide (Dy2O3) Powder

Dysprosium oxide or dysprosia with chemical composition Dy₂O₃, is one of the rare earth oxide families, is a white slightly hygroscopic powder, and it is highly insoluble and thermally stable. The structure of Dy₂O₃ takes a cubic crystal structure below 1870 °C and monoclinic and/or hexagonal structures above this temperature. Dy₂O₃ nanoparticles show interesting paramagnetic, optical, catalytic, and electronic properties. The application areas of Dy₂O₃ are; 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, as a dopant in fluorescent and glass materials, 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.
