Europium Oxide is white to slightly pink powder
| [Uses]
Europium oxide is now widely used as a phosphor activator, and europium activated yttrium vanadate is in commercial use as the red phosphor in color TV tubes. Europium oxide nanopowder acts as phosphors for lamps. It is used as a fluorescent label in immunoassay for atrazine. It is also used in color TV, X-ray, glass, crystal and other luminescent materials. | [Application]
Europium oxide, (Eu2O3), a compound of europium, is added to infra-sensitive phosphors to enhance the red colors on TV and computer-monitor picture tubes. It is also added to fluorescent light tubes to increase their efficiency, as well as to some materials to make lasers. Since it is a good neutron absorber, it is part of nuclear reactor control rods. | [General Description]
Europium Oxide, also called Europia, is used as a phosphor activator, color cathode-ray tubes and liquid-crystal displays used in computer monitors and televisions employ Europium Oxide as the red phosphor; no substitute is known. Europium Oxide (Eu2O3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for Yttrium-based phosphors. Europium Oxide is also applied in speciality plastic for laser material. | [reaction suitability]
