Representative TEM images of C-ZW nanorods. (a, b) Low and high magnifications. (c) TEM image of an individual C-ZW nanorod. Inset shows the schematic presentation of a ZnWO4/carbon core/shell-structured nanorod. (d, e) HRTEM images of an individual nanorod in the open-square regions, at the top and side of (c), respectively. (f) SAED pattern taken along the <001> zone axis. (By HW Shim et al.).
