Application of Europium Oxide
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.
