摘要
应用光谱技术研究铽及铕与水杨基羟肟酸所形成的配合物的发光性能,并探讨配合物的形成,以及溶剂、pH值及稀土含量对发光强度和能量传递的影响。
The new coordination compounds of rerbium and europiumion were prepared in the reaction of terbium and europium chloride with salicylhydroxamic acid(SHA) in slightly acidic medium respectively. The new coordination compounds were investigated by absorption, infrared spectroscopy, fluorescence spectroscopy. It was discussed that how the coordination compounds were formed and the influence of solvents and pH and rare earth loading on fluorescence intensity and energy transter efficiency.
