▎ 摘　　要

A novel high luminescent performance of graphene oxide-rare earth hybrid material was prepared using a noncovalent approach. Herein, a heteronuclear rare earth complex were revealed in which the benzoic acid (BA) and 1,10-phenanthroline hydrate (Phen) coordinated with Sm3+ and Gd3+, which was used to functionalize graphene oxide sheets (GOSs). The as-prepared products were characterized via Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscope, fluorescence spectrometer, decay lifetime and thermogravimetric analysis. The hybrid materials exhibited strong luminescence intensity, long lifetime and good thermal stability. Besides, Gd3+ ions had a strong sensitizing effect on materials and played a significant role in improving the luminescence intensity. The presence of GOSs did not quench the fluorescence performance of hybrid materials. Moreover, their fluorescence properties of Sm3+ and Gd3+ with different molar ratios were also studied.
