%X Polysiloxane with amino group as the functional side chain was prepared via equilibrium polycondensation reaction. It was modified with salicylaldehyde and then incorporated with lanthanide ions (Dy3+ and Sm3+) to obtain two luminescent functionalized polysiloxane¨Clanthanide composite materials. The structures and properties of products were characterized by Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, ultraviolet¨Cvisible absorption spectroscopy, fluorescent emission spectroscopy, and thermogravimetric analysis. The results show that two kinds of lanthanide ions were all incorporated successfully with the functionalized polysiloxanes. The coordination effect exists between the nitrogen atoms on the ligand and the lanthanide ions. In addition, the green and red light emissions that are characteristic of Dy3+ and Sm3+ were achieved
