Nano Europium Oxide Eu2O3 CAS 1308-96-9 For Phosphor Activator

Nano europium oxide is a rare earth oxide powder with high purity, small particle size, usually between 1 and 100 nanometers, and unique physical and chemical properties. It exhibits strong photoluminescence properties in the field of optics, and is widely used as an activator of phosphors, especially red phosphors for color television sets, and phosphors for high-pressure mercury lamps. In addition, nano europium oxide is also used in the fields of tricolor phosphor, display backlight, optical fiber dopant, etc., which can improve the transmission performance of optical fiber. In the field of electronics and magnetism, nano europium oxide also shows unique properties and is expected to be used in field effect transistors, solar cells and magnetic recording, magnetic sensors, etc.
