摘要: 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 small angle X-ray diffraction (XRD), transmission electron microcopy (TEM), fourier transform infrared spectrometry (FT-IR), and photoluminescence spectroscopy (PL). structure of the composites characterized XRD, which reveals is maintained functional groups have introduced into mesostructure. TEM photograph sample future shows ordered after grafting. FT-IR spectra improve RhB has successfully silica. PL product indicate emission spectrum shift to lower wavelength
