制备了苯甲酸钐/聚氨酯复合材料,并对其荧光性能进行了研究,获得了复合材料荧光强度与稀土质量分数间的依赖关系。结果表明,选择易于与稀土离子配位的有机基体与稀土有机配体进行熔体共混可显著提高二者相容性,可以获得稀土离子质量分数较高、分布较为均匀的稀土/高分子复合材料。
The samarium / polyurethane composite was prepared and its fluorescence properties were studied. The dependence of the fluorescence intensity of the composite on the mass fraction of rare earth was obtained. The results show that the compatibility between rare earth organic ligands and organic matrix which is easy to coordinate with rare earth ions can improve the compatibility between the two. It is possible to obtain rare earth / polymer composite with higher content of rare earth ions and more uniform distribution material.
