Abstract

Four complexes of Eu

and Tb

ions with 2

2'-dipyridyl (Dipy) and 1

10-phenanthroline (Phen) were synthesized in the absolute ethanol solutions

and the fluorescence properties of the complexes were studied.With respect to Dipy

Phen has higher electron density in the conjugated system with the result of a higher orbital overlap and consequently an easier transfer of energy to the rare earth ions

which make the fluorescence intensity of Phen complexes be stronger than that of Dipy complexes.Moreover

the high resolution emission spectra of Eu

measured at 77K indicate that the symmetry of Eu

sites in Eu(Phen)

·2H

O and Eu(Dipy)
