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%.
