Abstract

A series of Y

10-phenanthroline were synthesized in anhydrous alcohol. Elemental analysis and rare earth complexometic titration showed that the composition of the complexes are Tb

0.2 and 0.1). The IR absorption spectra indicated that the rare earth ions are bounded with the oxygen atoms of phenoxyacetic acid and phenoxy

and with two nitrogen atoms of 1

10-phenanthroline. Thermogram and thermogravimetric analysis indicated that the complexes release coordinated water at about 274 ℃ and they are stable below 576 ℃. Fluorescent spectra showed that the fluorescence intensity of the series Tb

complexes can be greatly enhanced if some of terbium ions in the complexes are substituted by Y

. The fluorescence lifetime of the complexes exhibits the similar feature to the fluorescence intensities.
