摘    要:本文研究了Ce3+-PMMA及Ce3+—PMA18·C·6两个高分子络合物发光材料的荧光激发过程以及激发过程与高分子结构的关系。通过荧光寿命、荧光光谱以及时间分辨光谱分析表明,在Ce3+—PMMA络合物体系中,Ce3+的荧光发射主要是来自高分子配体的能量传递,而对于Ce3+—PMA18·C·6粉末络合物体系,Ce3+发光的能量主要是来自入射光的直接激发。文章对上述两个稀土高分子络合物的激发机制的差异也做了较为详细地描述。

关 键 词:  络合物  发光  激发过程

Abstract:Energy transfer in rare earth (RE)-organic complexes materials and their luminescence properties have obtained extensive attention in the recent years. Studies of luminescence regarding to polymer compelxes of RE are particularly interesting. We have demonstrated that the energy transfer from the bpy (2,2’-bipyri-dine) to the central Ce3+ ion for the Ce3+-bpy complex solution and reported that the complexation of Ce3+ with the polemers and the fluores cence properties of the compexes in the preceding papers.In this paper, we described relation between the excitation process of Ce3+ fluorescence and the structures for the two complexes. The polymer complexes of Ce3+ are Ce3+-polymethylmethacrylate, Ce3+-PMMA and Ce3+-poly-(2-methacryloyloxymethy-1,4,7,10,13,16-hexaoxacyclotodecane), Ce3+-PMAl8·C·6,respectively.
