摘要
A new complex Tb(IB)_3(phen)·2H_2O that gives off green fluorescence was synthesized. The results show that the strong fluorescence emitting of 490 and 545 nm for Tb 3+ in the Tb(IB)_3(phen)·2H_2O complex is related to the transitions 5D_4-7F_6 and 5D_4-7F_5, respectively. The results indicate that the complex is concentrated on the nuclei regions in the section of onion toot tip tissues and the nuclei are high lighted under fluorescent microscope. It is possible that the Tb(IB)_3(phen)·2H_2O complex can be developed as a fluorescent dye in biological and pathological studies.
