Name: Nano europium oxide CAS: 1308-96-9
Molecular formula: Eu2O3 Molecular weight: 351.9
Description: Nano europium oxide is white powder with light pink color, insoluble in water and soluble in acid. The preparation method of nanometer europium oxide is that europium oxide precursor is prepared with EuCl3 as raw material and polyvinyl alcohol as dispersant by ammonium bicarbonate precipitation process, then methanol is added, and it is heated to decompose, the europium oxide Eu2O3 obtained is crushed and screened to obtain nanometer europium oxide.

Used: Used in the manufacture of additives of phosphor activator, colored lenses and optical filters. Most of nano europium oxide is used in phosphor. Eu3+ is used as activator of red phosphor and Eu2+ is used as blue phosphor. Recently, europium oxide nanoparticles have also been used as stimulated emission phosphors in new X-ray medical diagnosis systems. Nano europium oxide can also be used to make colored lenses and optical filters, and used for magnetic bubble storage devices.
