Encapsulation and photoluminescent property of [Eu(bpy)2]3+ in mesoporous material HMS.
The photoluminescence properties of europium (III) ions and its complex with 2,2'-bipyridine, [Eu(bpy)2]3+, encapsulated in the hexagonal mesoporous material HMS are reported. X-ray diffraction spectra, ICP analysis, IR spectra, N2 adsorption measurements, and the photoluminescence spectra were used to characterize the corresponding impregnated samples. All the impregnated HMS samples exhibit the typical photoluminescence properties of Eu3+ when excited with a xenon lamp. These results show that HMS is an efficient host lattice for the photoluminescence of the europium (III) ions bound to an appropriate ligand.
