We investigated a two‐step method to deposit the ZnO‐based nanostructure films, including nanorods and nanoflowers. In the first step, sputtering method was used to deposit the ZnO films on SiO 2 /Si substrates as the seed layer. In the second step, Zn(NO 3 ) 2 –6H 2 O and C 6 H 12 N 4 were used as precursors and hydrothermal process was used as the method to synthesize the ZnO films. After that, the ZnO films were measured by an X‐ray diffraction pattern and a FESEM to analyze their crystallization and morphology. We had found that the ZnO films had three different morphologies synthesized on ZnO/SiO 2 /Si substrates, including irregular‐plate structure films, nanorod films, and beautiful chrysanthemum‐like clusters (nanoflower films). We would prove that the face direction of ZnO/SiO 2 /Si substrates in the hydrothermal bottle and deposition time were two important factors to influence the synthesized results of the ZnO films.
