Abstract:
[Eu(bpy)2]3+(bpy:2, 2’-bipyridine)was encapsulated in hexagonal mesoporous materials MCM-41 and HMS.XRD spectra, ICP analysis, IR spectra, N2 adsorption measurements and the photoluminescence spectra were used to characterize the corresponding impregnated samples.After the impregnation of [Eu(bpy)2]3+, the BET surface, pore diameters and pore volume of the impregnated samples were decreased.All the impregnated samples exhibited the typical photoluminescence of Eu3+ when excited with a xenon lamp.Compared with the impregnated HMS, the impregnated MCM-41 samples show higher photoluminescence efficiency for the impregnation of [Eu(bpy)2]3+. It suggests that MCM-41 is a more efficient host for the photoluminescence of europium complexes than HMS.
