XRD diffraction pattern and side-view SEM and HRTEM images of ZnO nanoflowers. (a) XRD diffraction pattern of the as-grown ZnO nanoflowers; (b) the side-view SEM image of the as-grown sample, showing that the ZnO is a flower-like; (c) HRTEM image of the stalk of the nanoflowers. The inset (c) shows the DDPs of the marked region.
