Thulium(III) bromide is a crystalline compound of one thulium atom and three bromine atoms. [5] The salt is a white powder at room temperature. [1] It is hygroscopic. [6]
Thulium(III) bromide is used as a reagent for the complexation of lanthanide bromides with aluminium bromide, and as a reactant for preparing alkali metal thulium bromides. [2] It is also used to create discharge lamps that are free of mercury. [7]
