Improve the Optical Properties of Rhodamine B by Encapsulating in Al-MCM-41

Abstract:

M-MCM-41 (M = Al, Cu, Cr, Ti) were synthesized by hydrothermal method and characterized by XRD. Rhodamine B molecules were encapsulated into these mesoporous molecular sieves by impregnation method. Steady fluorescence measurements indicated that doping of Al ions into MCM-41 enhanced largely the fluorescence intensities, but more Al decreased the fluorescence intensities resulting from the formation of Al₂O₃.
