稀土配合物 水杨酸 红外光谱 紫外光谱 荧光 Complex of rare earth Salicylic acid Infrared spectrum Ultraviolet spectrum Fluorescence spectrum
摘要
合成了一系列稀土水杨酸配合物．分别研究了配合物的红外光谱(IR)，紫外(UV)及荧光光谱(FS)性质．红外光谱研究表明，稀土和水杨酸主要通过羧基进行配位，而紫外光谱显示配合物中水杨酸和稀土离子之间的能量传递是主要过程；配合物的荧光性质研究发现水杨酸钆，水杨酸铽，水杨酸镝分子内能量传递效率高，具有很强的荧光性质．
Abstract
A series of rare earth complexes with salicylate were synthesized and studied by infrared spectrum,ultraviolet spectrum,fluorescence spectrum. The results of infrared spectrum indicates that the rare earth ions coordinated with salicylate by carboxyl. As for ultraviolet spectrum of the complexes,energy transfer between salicylate and rare earth ions is the primary process;fluorescence spectrum,as a comparison,the complexes salicylate gadolinium (Ⅲ),salicylate terbium (Ⅲ),salicylate. dysprosium (Ⅲ)have higher efficiency of intermolecular energy transfer and stronger fluorescence character.
