Europium oxide (also known as europia) is a chemical compound with the formula Eu2O3. It is a rare earth oxide and a white solid material with a cubic crystal structure. Europium oxide is used as a material for making phosphors for use in cathode ray tubes and fluorescent lamps, as a dopant in semiconductor devices, and as a catalyst. It is also used in the production of ceramics and as a tracer in biological and chemical research.

Application

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.
