摘　　要：以对苯二甲酸(H2L)为配体,合成了系列(Eu1-xYx)2L3.3H2O固体粉末配合物.通过元素分析、紫外吸收光谱、X射线衍射和红外光谱确定了配合物的组成和结构,并通过荧光光谱研究了它们的荧光性质.结果表明钇掺入配合物后,能增强Eu3+的特征荧光,当铕与钇的摩尔比为0.05∶0.95时荧光强度最强.A series of complexes （Eu1-xYx）2L3 ·3H2O have been synthesized using p-phthalic acid as ligand. Their compositions and structures were determined by elemental analysis, UV spectra, and FT- IR spectra, respectively. Their luminescent properties were also investigated by photoluminescence （PL） spectra. Highly enhanced characteristic emission corresponding to Eu^3＋ was observed by the incorporation of y^3＋ into the complex. A maximum PL intensity was obtained when the mole ratio of europium to yttrium was 0.05： 0.95.
