Europium

Chemical element symbol is (Eu) and atomic number 63.

Europium is a Rare Earth Metal classified in the group of Light Rare Earth Elements (LREE).

Paul Emile Lecog de Boisbaudran rubs his eyes in amazement in 1890, when he looks at the spectral line of a concentrated samarium and gadolinium closer. He was looking at something unknown, that nobody had seen before him. Six years later, Eugene-Anatole Demarcay demonstrated the existence of a new element spectroscopy and first isolated in 1901. The Europium was born. Demarcay companion Marie Curie, then discovered an element that remains one of the most interesting and rare earth that is, with americium, only to be designated by the name of a continent.

The Europium is the lightest of all heavy metals. It auto-ignite and burns causing a bright red flame. As cerium, Europium exists in two different forms of oxidation, which gives it more flexibility than most other Rare Earths.

Because of its important role in the production of LED, LCD and lighting devices, Europium is one of the most rare earth phosphors. As cerium, Europium exists in two different forms of oxidation, which gives it more flexibility than most other Rare Earths.
