用硝酸铕、水杨酸与邻菲罗啉为原料合成了配合物Eu(Sal)2(phen)2(NO3),考察了配体用量和溶剂用量等因素对反应的影响。通过元素分析、红外光谱和紫外光谱确定了配合物的组成及结构,并通过荧光光谱对其荧光性质进行了研究。 Eu (Sal) 2 (phen) 2 (NO3) was synthesized from europium nitrate, salicylic acid and o-phenanthroline. The effects of the amount of ligand and the amount of solvent on the reaction were investigated. The composition and structure of the complex were determined by elemental analysis, infrared spectroscopy and ultraviolet spectroscopy. The fluorescence properties of the complex were also studied.
