Photoluminescence property of Eu(bpy)23+ dispersed in mesoporous materials SBA-15

摘要

[Eu(bpy)2]3+(bpy: 2,2'-bipyridine) was encapsulated in mesoporous materials SBA-15. XRD spectra, ICP analysis, IR spectra, N2 adsorption-desorption and the photoluminescence spectra were used to characterize the corresponding samples. With the increasing of the content of the impregnated [Eu(bpyh]3+, the surface area and pore volume of the impregnated sample decreased. All the impregnated samples exhibited the typical photoluminescence of Eu3+ when excited with a xenon lamp. It was suggested that the [Eu(bpy)?]3+ has been successfully introduced into the pores of SBA-15.
