中文摘要	we report on the preparation of luminescent silica mesoporous molecular sieves (mcm-48) activated by the europium complex eu(dbm)(3) . 2h(2)o (where dbm = dibenzoylmethane), using a simple wet impregnation method. different concentrations of eu(dbm)(3) . 2h(2)o were introduced into the mcm-48 cubic structure, and the resulting samples were washed with ethanol for different times. uv-vis absorption measurements and thermogravimetric analysis were used to estimate the amount of eu complex that has been incorporated within the pores of the mcm-48 host. the various samples were characterized by x-ray powder diffraction (xrd), infrared spectroscopy, diffuse reflectance (dr) and fluorescence measurements. the results reveal that eu complexes have been successfully introduced into the pores of mcm-48 without disrupting the structure. all the impregnated mcm-48 materials show the typical red luminescence of eu3+ when excited with a uv lamp. shifts of the absorption maxima were observed in the dr and fluorescence excitation spectra and will be discussed in relation with guest-host interactions between the organic complex and the silica matrix. the decay profiles of the europium luminescence in the different samples were also measured and discussed.
