Graphical abstract: Display Omitted Highlights: ► A simple approach to obtain Gd{sub 2}O{sub 3} nanoparticles onto RGO sheets. ► Gd{sub 2}O{sub 3} nanoparticles could be bonded with RGO by the residual C-OH or COOH groups. ► The as-prepared Gd{sub 2}O{sub 3} nanoparticles are well-dispersed and in the size of 10–50 nm. -- Abstract: High quality and dispersible rare-earth oxides (RE{sub 2}O{sub 3}) nanocrystals have drawn great attention because of their potential applications in the optical, electrical and biological fields. Here, we demonstrated a simple approach for the production of gadolinium oxide (Gd{sub 2}O{sub 3}) nanoparticles onto the surface of reduced graphene oxide (RGO) sheets by the chemical and the subsequent thermal reduction reactions. The residual oxygen functionalities derived from the reduction of graphene oxide (GO) played an important role to complex Gd{sub 2}O{sub 3} nanoparticles with RGO sheets. And the as-synthesized Gd{sub 2}O{sub 3} nanoparticles are uniform and well-dispersed with their particle size in the range of 10–50 nm. The approach would open up a new window for simple and effective synthesis of high quality RE{sub 2}O{sub 3} in nano scale.
