Applications
UsesDysprosium(III) fluoride is specialized uses in laser glass, phosphors, Dysprosium halide lamp and also as the main raw materials for making Dysprosium metal.
UsesThulium(III) acetate hydrate is a moderately water soluble crystalline Thulium source that decomposes to Thulium Oxide on heating. It is generally immediately available in most volumes. It can also be used in portable X-ray devices that has been bombarded in a nuclear reactor as a radiation source. The other main application is used for optical fiber.
