History

Europium was first found by Paul Émile Lecoq de Boisbaudran in 1890. In 1896, French chemist Eugène-Antole Demarçay identified spectroscopic lines in ‘samarium' caused by europium. He successfully isolated europium in 1901 using repeated crystallizations of samarium magnesium nitrate. Europium was named after Europe

DiscoverersEugène Demarçay
Discovery LocationFrance
Discovery Year1901
Etymology (Name Origin)Named for the continent of Europe.
Pronunciationyoo-RO-pi-em (English)
Europium is considered to be mildly toxic
Europium is the most reactive rare earth element

Uses

Europium is used in the manufacture of fluorescent glass. It is also used in the anti-counterfeiting phosphors in Euro banknotes. Europium-doped plastic has been used as a laser material. Europium isotopes are good neutron absorbers and are used in nuclear reactor control rods. Used with yttrium oxide to make red phosphors for color televisions.

Sources

Obtained from monazite sand, which is a mixture of phosphates of calcium, thorium, cerium, and most other rare earths.
