摘要
采用水作溶剂,用2,3,5-吡啶三酸与稀土铕的氯化物反应合成了一种配合物,通过EDTA络合滴定分析,确定了配合物中铕离子的含量;并对配合物进行了熔点、红外光谱测定,测试了固态铕配合物的荧光激发和发射光谱。结果表明,该配合物具有良好的光致发光性质。
An europium complex with pyridine-2,3,5-tricarboxylic acid was synthesized in water by the reaction of pyri-dine-2,3,5-tricarboxylic acid and europium chloride.The content of europium was determined by complexometric titration with EDTA.The melt point and IR spectrum of the complex were also tested.The excitation spectrum and emission spectrum were tested and the solid complex were determined.The results show the complex displays good photoluminescent properties.
