A series of new diamide ligands were introduced into the complexes of Eu(NO 3) 3 and Tb(NO 3) 3 so as to improve the fluorescent properties. The fluorescent properties of the resulting complexes were investigated. It was found that the complexes subject to the excitation of UV light showed characteristic emission of europium and terbium ions, in particular, the Tb complexes had very much intense fluorescence.
