Europium - Element information, properties and uses | Periodic Table

Uses. Europium is used in the of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow. Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light.
