Synthesis and Luminescence of Complexes EuxY1-x（phen）L3
摘要
A series of binuclear complexes with different molar ratio of europium to yttrium with cinnamic acid and o-phenanthroline were synthesized in anhydrous alcohol. Elemental analysis shows that the composition of the complexes are EuxY1-x(phen)L3 (L: C6H5CH=CHCOO, x=1.0, 0.7, 0.5, 0.3 and 0.1). The IR absorption spectra indicate that cinnamate is coordinated to the rare earth ions and chemical bonds are formed between rare earth ions and nitrogen atoms of o-phenanthroline. Fluorescent spectra show that the emission of Eu3+ ion can be greatly enhanced if some of europium ions in the complexes are substituted by yttrium ions.
