稀土Sm配合物/聚氨酯丙烯酸酯复合材料的制备与性能研究

Preparation and characterization of Sm complex/polyurethane acrylate

通过扩散法制备了具有一维结构的Sm配合物，在合成聚氨酯丙烯酸酯大分子单体的基础上原位（InSitu）聚合获得一系列不同配合物含量（0．5％～12．0％）的聚氨酯丙烯酸酯复合材料，并对材料进行了相关光热性能的表征。研究结果表明，该系列复合材料在370nm处被激发，在592nm处能够产生稀土Sin的特征发射峰，而且发光强度与复合材料中配合物的含量相关联。该复合材料有望作为一种新型发光材料而被广泛研究。

A one-dimensional Sm complex was synthesized by adopting diffusion method. The composites of Sm complex/polyurethane acrylate were prepared by in-situ polymerization based on macromonomers of polyurethane acrylate, and the thermal and luminescent properties of the materials were characterized. The results indicated that the composites could emit Sm characteristic fluorescence with peak wavelength at 592nm under excitation at 370nm. Photoluminescent in-tensity of them was found to be influenced with the content of Sm complex It would be used as a new promising lumines-cent material.
