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.
The measurement of the fluorescence, UV-Vis absorption, FTIR and XPS spectroscopy demonstrated that the oxygen atom in polydimethylsioxane（PDMS） can coordinate with Tb^3＋, forming the complex of Tb^3＋ and PDMS complex（Tb3＋-PDMS）. It was found that after Tb^3＋-PDMS is formed, both the fluorescence emissions of PDMS and Tb^3＋ in the complex are enhanced comparing with that of Tb^3＋ and PDMS. The enhancement of the fluorescence intensity of the complex is related to the content of Tb^3＋ in the complex. When the content of Tb^3＋ in the complex is 2.0%（w）, the fluorescence intensity of the complex is largest. The fluorescence intensity can be enhanced by 1547%.
