Terbium Nitrate Hydrate Tb(NO3)3 5H2O CAS 57584-27-7 For Fluorescent Compounds
Name: Terbium nitrate, Terbium nitrate hydrate Molecular formula: Tb(NO3)3·5H2O
CAS: 57584-27-7 Molecular weight: 435.02
Description: Terbium nitrate is a colorless monoclinic crystal, which decomposes at high temperature and can be dissolved in water, ethanol, acetone and esters. It can be extracted into organic solvent phase by Tributyl phosphate. Its anhydrous salt is easily soluble in anhydrous amine, nitrile and other polar organic solvents. The preparation method is to dissolve terbium metal in nitric acid, or to react terbium oxide with nitric acid, and to crystallize terbium nitrate hydrate from aqueous solution.

Uses: Terbium nitrate reacts with 1,1,1′,1′ - tetra (pyridine-2-carboxylic acid ester) trimethylpropane to form a complex of [Tbl(NO3)](NO3)2 · 2H2O. Under the excitation of ultraviolet light, the complex emits strong Tb3+ characteristic fluorescence. The fluorescence lifetime of Tb3+ 5D4 level in the complex is longer. Terbium oxide assembled carbon nanotube composite.
