▎ 摘　　要

We used a hydrothermal method combined with a graphene oxide (GO)/ZnO film to fabricate large-surface area ZnO nanorods with fast UV response. The photocurrents of ZnO nanorods grown on ZnO film and GO/ZnO film, respectively, were about 0.15 and 1.05 mA. The absorbance of ZnO nanorods grown on a GO/ZnO film was also larger than that of ZnO nanorods grown on a ZnO film. The introduction of GO can be decreased near-band-edge (NBE) emission intensity in photoluminescence spectra, which indicates the transfer of electrons from ZnO nanorods to the surface of the GO (quenching). Therefore, the presence of GO was increased both light absorbance and photocurrent of the ZnO nanorods, and was decreased NBE emission intensity.
