APPICATIONS OF EUROPIUM
Europium is utilized primarily for its unique luminescent behavior. Excitation of the Europium atom by absorption of ultra violet radiation can result in specific energy level transitions within the atom creating an emission of visible radiation.
In energy efficient fluorescent lighting, Europium provides not only the necessary red, but also the blue. Several commercial blue phosphors are based on Europium. See additional discussion of phophors.
Its luminesence is also valuable in medical, surgical and biochemical applications.
