In 1901, Eugene Antole Demarcay discovered a new element from "samarium" and named it Europium. This is probably named after the term Europe.
Most of the europium oxide is used for fluorescent powders. Eu3+is used as an activator for red phosphors, and Eu2+is used for blue phosphors. Currently, Y2O2S: Eu3+is the best fluorescent powder for luminescence efficiency, coating stability, and recovery cost.
In addition, improvements in technologies such as improving luminous efficiency and contrast are being widely applied.
In recent years, europium oxide has also been used as a stimulated emission phosphor for new X-ray medical diagnostic systems. Europium oxide can also be used to manufacture colored lenses
And optical filters, used in magnetic bubble storage devices, can also be used in control materials, shielding materials, and structural materials of atomic reactors.
