Europium Oxide

Brief Description of Europium Oxide Powder Eu2O3

Europium(III) oxide (Eu2O3), is a chemical compound of europium and oxygen.

Europium Oxide powder is a highly insoluble thermally stable Europium source suitable for glass, optic and ceramic applications.

Europium fluorescence is used in the anti-counterfeiting phosphors in Euro banknotes.

It may be formed by ignition of europium metal.

It can react with acids to form the corresponding europium(III) salts.
