Main Uses:

Phosphor raw materials:
It is used in the fields of color cathode-ray tube, color TV picture tube, computer display, three-primary fluorescent lamp and new long afterglow display, as well as new X-ray medical diagnosis system. Europium oxide can also be used in the manufacture of colored lenses, optical filters, magnetic bubble storage devices;

It is also a very important material in the control materials, shielding materials and structural materials of atomic reactors. It is mainly used as phosphor for color TV, terminal display, X-ray screen and fluorescent lamp. It is used as a colorant in the glass industry to make the glass orange-red, to produce anti-radiation glass, and to be used as an additive for quartz fiber.

Europium oxide is used as an activator for many fluorophores. Such as Eu3+, used for colorimetric tube activation Y2O3 or Y2O2S, and high pressure  lamp activation YVO4. In the nuclear industry, europium oxide is used as a neutron absorber.
