摘要

In this paper, a core-shell structure of Au_nanoparticle@mSiO₂ with controllable thickness of silica was synthesized by a modified one-pot process and then europium complex of PABI-Eu was grafted on the surface of Au_nanoparticle@mSiO₂ nanostructure to successfully construct the resulting Au_nanoparticle@mSiO₂@PABI-Eu nanocomposite. The spectroscopic result revealed that the emission intensity of the Au_nanoparticle@mSiO₂@PABI-Eu nanocomposite is highly dependent on the thickness of silica. The enhancement factor of 4.20 is achieved at 30 nm thickness of silica between Au nanoparticle and PABI-Eu complex.
