▎ 摘　　要

In this study, E(III) complex nanocrystals had grown on graphene oxide (GO) by pi-pi stacking. Fourier transform infrared spectroscopy (FTIR), transmission electron morphology (TEM) and X-ray diffraction (XRD) were used to demonstrate the successful growth of Eu(III) complex nanocrystals on GO surface. Investigations using fluorescence spectroscopy proved the fluorescence property of the composite and the fluorescence quenching concentration of Eu3+ was 18wt%. Thermogravimetric analysis (TGA) showed that the thermal stability of the composite had been remarkably improved comparing with pure complex.
