▎ 摘　　要

Graphene oxide sheets (GOSs) functionalized with rare-earth (RE) complexes were prepared using a noncovalent approach. The adsorption of RE complexes onto GOSs, as well as the individual nature of the hybrids, was confirmed. The GOS-RE complex hybrids and their dispersion can emit bright red luminescence, which makes them useful in many practical fields, such as biological labeling and anti-counterfeiting.
