Europium was discovered in 1901 by French chemist Eugène-Anatole Demarçay. It gained practical use only in the mid-20th century, when scientists realized it can produce two different colors, which correspond to two different oxidation states, Eu 3+ (orange-red) and Eu 2+ (blue)

The type of Ultraviolet light and the color of visible light is determined by its wavelength. The unit of measurement for light wavelengths is the nanometer (nm). Ultraviolet light is generally considered to be from 200 nm to 400 nm.
