Usage:
Europium Metal, is very valuable material in control rods for nuclear reactors due to that it can absorb more neutrons than any other elements. It is a dopant in some types of glass in lasers and other optoelectronic devices. Europium is also used in the manufacture of fluorescent glass. 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.
