【摘要】 以香豆素为主配体,邻菲罗啉、三苯基氧化磷、氨替吡啉、水这些中性配体作为第二配体,合成了不同稀土离子(Eu3+、Tb3+、Sm3+、Dy3+)的配合物,通过元素分析、红外、紫外、荧光光谱等分析,表征了这些配合物的组成结构和发光性能。结果表明,在所合成的配合物中,香豆素与铕﹑邻菲罗啉形成的配合物发光强度最强,对其掺入不同比例的钆,发现可改变该配合物的发光强度。

【Abstract】 Some different ternary complexes of rare earth(Eu3+,Tb3+,Sm3+,Dy3+)with coumarin and water,Phen,TPPO,Ant were synthesized by homogenous precipitation.Their composition and structure were characterized by means of elemental analysis,IR spectra,UV-Vis and fluorescent spectra.The results indicated that Eu(Coumarin)3Phen could emit the strongest red fluorescence among these complexes.The optimum proportion was found in Eu(Coumarin)3Phen with variated concentration of Gd3+ as dopant,which could enhance the emitting fluorescence.Furthermore,its mechanism was proposed.
