Europium is most commonly extracted from monazite and bastnasite ores.
Europium is the most reactive of the rare earth elements. It rapidly oxidizes in air: bulk oxidation of a centimeter-sized sample occurs within several days. It resembles calcium in its reaction with water.
Europium oxide is widely used as a red or blue phosphor in television sets and fluorescent lamps, as an activator for yttrium-based phosphors, for manufacturing fluorescent glass and as anti-counterfeiting phosphor in banknotes.
