Multilingual: EuropiumHydroxid, Hydroxyde De Europium, Hydroxide Del Europium		 Europium Hydroxide, also called Europium Hydrate, is used as a phosphor activator for color cathode-ray tubes and liquid-crystal displays used in computer monitors and televisions employ Europium Oxide as the red phosphor. In energy efficient fluorescent lighting, Europium provides not only the necessary red, but also the blue. Several commercial blue phosphors are based on Europium for color TV, computer screens and fluorescent lamps. A recent (2015) application of Europium is in quantum memory chips which can reliably store information for days at a time; these could allow sensitive quantum data to be stored to a hard disk-like device and shipped around the country.
