Sweet Stocking stuffer, Christmas gift Great chemistry gift Amazing science gift The Facts of Thulium Thulium element 69 is a chemical element; a silvery white rare earth metal. The least abundant metal of the rare earth metals. Tm3+ ions emit a strong blue luminescence when excited. Thulium tarnishes slowly in dry air to form the oxide and reacts with water to form the hydroxide and hydrogen gas. Thulium is used to dope yttrium aluminum garnets (YAG) used in lasers. Thulium is also used in alloys with other rare earth metals. Thulium is used in euro banknotes for its blue fluorescence under UV light to defeat counterfeiters.
