| 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 areEuxY1-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 Eu^3 ion can be greatly enhanced if some of europium ions in the complexes are substituted by yttrium ions.

| Abstract: | 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 Eu x Y 1- x (phen)L 3 (L: C 6H 5CH=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 Eu 3+ ion can be greatly enhanced if some of europium ions in the complexes are substituted by yttrium ions. |
