In this study, we report the fabrication of sol–gel prepared ZnO nanorods through the use of vapor-confined face-to-face annealing (VC-FTFA) in which mica was inserted between two films, followed by annealing using the FTFA method. LZO nanorods are regrown when lithium chloride is used as the solvent because ZnCl2 and LiCl vapors are generated. The near-band-edge emission intensity of the LZO nanorods is enhanced through annealing using the VC-FTFA method and is increased by a factor of 6 compared to that of LZO thin films annealed in open air at 600 °C. Our method may provide a route toward the facile fabrication of ZnO nanorods.
