| 摘 要： | 采用水做溶剂,用2,3,5-吡啶三酸做配体和重稀土铽、镝、铒、镱、镥、钇六种稀土元素的氯化物在常温下反应合成了六种重稀土的配合物。通过EDTA络合滴定分析,确定了六种配合物中稀土离子含量;并对配合物进行了熔点测定、红外光谱测试,并测试了铽和镝配合物的光致发光性质,结果表明,铽和镝配合物在紫外光的激发下具有良好的发光性质。

| Abstract: | Six heavy rare earth complexes of Tb3+,Dy3+,Er3+,Yb3+,Lu3+ and Y3+ with 2,3,5-pyridinetricarboxylic acid were synthesized in water at room temperature.The contents of the rare earth elements were determined by EDTA complexometric titration.In addition,the melt points and infrared spectra were tested.The photoluminescent properties of Tb3+ and Dy3+ complexes were also tested and the results show that they both emit strong fluorescence with excitation of ultraviolet rays. |
