Rhodamine B, a familiar organic dye, was embedded in mesoporous silica (MCM-41) that had been modified by (3-aminopropyl) triethoxysilane (APTES) through chemical bonding method. The materials were investigated by small angle X-ray diffraction (XRD), transmission electron microcopy (TEM), fourier transform infrared spectrometry (FT-IR), and photoluminescence spectroscopy (PL). The structure of the composites was characterized by XRD, which reveals that the mesoporous structure is maintained and the functional groups have been introduced into the mesostructure. The TEM photograph of the sample future shows that the ordered mesoporous structure is maintained after grafting. The FT-IR spectra improve that RhB has been successfully introduced into the mesoporous silica. The PL spectra of the product indicate that the emission spectrum shift to lower wavelength after grafting. © 2016
