| 摘 要： | 用多种谱学方法证明聚二甲基硅氧烷(PDMS)中的氧原子能与Tb3+键合生成Tb3+和PDMS的配合物(Tb3+-PDMS), 并发现生成配合物后, PDMS和Tb3+的荧光发射同时得到增强. 荧光强度的增强与配合物中Tb3+含量有关, 当配合物中Tb3+的含量为2.0%(w)时, 配合物的荧光强度最大, 可增强1547%左右.

| Abstract: | The measurement of the fluorescence, UV-Vis absorption, FTIR and XPS spectroscopy demonstrated that the oxygen atom in polydimethylsioxane(PDMS) can coordinate with Tb3 , forming the complex of Tb3 and PDMS complex(Tb3 -PDMS). It was found that after Tb3 -PDMS is formed, both the fluorescence emissions of PDMS and Tb3 in the complex are enhanced comparing with that of Tb3 and PDMS. The enhancement of the fluorescence intensity of the complex is related to the content of Tb3 in the complex. When the content of Tb3 in the complex is 2.0%(w), the fluorescence intensity of the complex is largest. The fluorescence intensity can be enhanced by 1547%. |
