Europium is a chemical element in the periodic table that has the symbol Eu and atomic number 63. It was named after the continent Europe.
Notable characteristics
Europium is the most reactive of the rare earth elements; it quickly oxidizes in air, and resembles calcium in its reaction with water. Like other rare earths (with the exception of lanthanum), europium ignites in air at about 150 °C to 180 °C. It is about as hard as lead and quite ductile.
Applications
There are few commercial applications for europium metal, although it has been used to dope some types of plastics to make lasers, as well as being used for screening for Down's syndrome and some other genetic diseases. Due to its ability to absorb neutrons, it is also being studied for use in nuclear reactors. Europium oxide (Eu2O3) is widely used as a red phosphor in television sets, and as an activator for yttrium-based phosphors. It is also being used as an agent for the manufacture of fluorescent glass. A salt of Europium is a component of the newer phosphorescent powders and paints, some of which will glow for days after a few minutes of exposure to light. Europium fluorescence is used to interogate biomolecular interactions in drug-discovery screens. It is also used in the anti-counterfeiting phosphors in Euro banknotes.
