| Abstract: | A novel hybrid inorganic-organic mesoporous luminescent material (phen) 2Eu/MCM-41 has been synthesized and characterized by XRD, IR, fluorescence and diffuse reflection spectra. In comparison with MCM-41, the hybrid mesoporous material has typical structure of MCM-41 and retains the same pore structure as MCM-41 after the assembly process. The hybrid mesoporous material shows characteristic emission spectra of Eu 3 under UV irradiation, but the excitation spectrum has shifted to blue region compared to that of pure rare earth complex. The decrease of site symmetry of Eu 3 has been found. The fluorescence lifetime of (phen) 2Eu/MCM-41 is longer than that of pure rare earth complex. The spectra of hybrid mesoporous material have been discussed. |
