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 cont...
