Synthesis and fluorescence spectra of complex of Eu-Y with cinnamic acid and o-phenanthroline |
| |
Abstract: | The complex of europium-yttrium with cinnamic acid and o-phenanthroline has been synthesized in anhydrous alcohol.Elemental analysis showed that the composition of the complex is (Eu 0.5 Y 0.5 )(Phen)L 3( L=C 6H 5CH CHCOO - ).The IR absorption spectra indicated that cinnamate was coordinated to the rare earth ions and the chemical bonds have been formed between rare earth ions and nitrogen atoms of o-phenanthroline.Fluorescence spectra excited by 338nm UV-light showed that the fluorescence emission of Eu 3+ ion was sensitized by Y 3+ ion,the sensitization of Y 3+ can enhance the fluorescence emission intensity of Eu 3+ ion. |
