Synthesis and luminescence property of rare earth complex nanoparticles dispersed within pores of modified mesoporous silica

A rare earth complex, Eu(AA)3Phen was successfully introduced into the pores of mesoporous silica, which was verified by X-ray photoelectron spectroscopy and nitrogen sorption isotherms. The rare earth complex dispersed in mesoporous silica displayed characteristic fluorescence emission of the pure rare earth complex, and the fluorescence emission was enhanced, especially for that with diamine treated mesoporous silica.
