▎ 摘　　要

The graphene oxide films have been fabricated by simply filtering the graphene oxide solution through the micropore filter. Then the flower-like ZnO grows on the graphene layer by immersing the seed-coated graphene oxide films in the dilute growing solution containing NH3 center dot H2O and Zn(NO3)(2)center dot 6H(2)O. The morphologies of the as-obtained ZnO deposited on the graphene oxide layer are characterized by using scanning electron microscope (SEM), X-ray powder diffraction (XRD) and photoluminescence (PL). The formation mechanism of the flower-like ZnO has also been investigated. The results show that the morphology of the finally-obtained ZnO is tunable by seeds, the concentration of growing solution and the reaction time. (C) 2011 Elsevier B.V. All rights reserved.
