Small chunks of Thulium metal on top of a 10 Euro bill. One photo is under a daylight lamp, the other photo is under a black (UV) light. The Euro bill has small fluorescent fibers striped in red, green, and blue. Thulium may be responsible for the blue fluorescence, according to the Wikipedia article about Thulium. The Guatemalan bill behind the Thulium sample is not confirmed to be made with Thulium, even though it also has fluorescent fibers. It was placed behind the sample for decoration.
