Application
Europium(iii) 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 used for producing fluorescent powder for color picture tubes, rare earth tricolor fluorescent powder for lamps, X-ray intensifying screen activators, etc. Europium Oxide is used as a red fluorescent powder activator for color televisions and fluorescent powder for high-pressure mercury lamps.
