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%.
