The rare earth complex Eu(TTA)3 was successfully encapsulated into MCM-41 mesoporous molecular sieve by the addition of the complex into the sol-gel mixture for the synthesis of MCM-41 mesoporous material under microwave radiation. The as-synthesized MCM-41-hosted Eu(TTA)3 mesophase was confirmed to possess hexagonally ordered mesostructure and a uniform crystal size of about 30 nm with XRD and HRTEM techniques. Moreover, the IR spectrum, photoluminescence effect and fluorescence lifetime of the Eu(TTA)3/MCM-41 hybrid were also studied. An increase in Stokes shift and no change in luminescence lifetime were observed to the resultant mesophase in comparison with Eu(TTA)3 in ethanol solution.
