Fluorescence of postgrafting Rhodamine B in the mesopores of rodlike SBA-15

Rhodamine B (Rh B) has been grafted into the channels of rod-like mesoporous silica SBA-15, which had been modified by organic silane with terminal amino group in CHCl3 solvent. The investigations of UV-vis, photoluminescence, and FT-IR confirmed the existence of Rh B in the channels of RSBA-15 (rod-like SBA-15). The composites show strong fluorescence and obvious blue-shift at the yellow wave band compared with Rh B in CHCl3.
