About Thulium Oxide

Oxide IonThulium Oxide is a highly insoluble thermally stable Thulium source suitable for glass, optic and ceramic applications. Thulium oxide is a solid compound and is pale green in color. Thulium Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Thulium emits blue upon excitation in flat panel screens and under X-ray bombardment emits both the 375 nm (ultra violet) and 465 (visible blue) wave lengths giving it useful applications in low radiation detection for detection badges and similar uses. Oxide High Purity (99.999%) Thulium Oxide (Tm2O3) Powdercompounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Thulium oxide is also available in pellets, pieces, sputtering targets, and tablets. Additional technical, research and safety (SDS) information is available.

Thulium Bohr ModelThe number of electrons in each of Thulium's shells is [2, 8, 18, 31, 8, 2] and its electron configuration is [Xe]4f136s2. The thulium atom has a radius of 176 pm and a Van der Waals radius of 227 pm.Elemental Thulium Picture In its elemental form, thulium has a silvery-gray appearance. Thulium is representative of the other lanthanides (rare earths) and similar in chemistry to yttrium. It is the least abundant of the rare earth elements. Thulium emits blue upon excitation, and is used in flat panel screens that depend critically on bright blue emitters. Thulium was discovered and first isolated by Per Teodor Cleve in 1879. It is named after "Thule," which is the ancient name of Scandinavia.
