碩士 === 國立暨南國際大學 === 應用材料及光電工程學系 === 102 === In this thesis, we used a non-vacuum method to produce a seed layer of ZnO nanorods which accretes on the various types of conductive and non-conductive substrate. The main ZnO NPs were grown hydrothermally with low temperature and pressure. Since we grow ZnO NRs by the hydrothermal method, the recrystallization status can be observed. We can monitor the type of crystallization and the quality of the ZnO NRs. For example, when we add the NaOH in the growing environment, the shape the ZnO become flower-like structure, which is distinct from the ZnO NRs. The experimental results indicate that, ZnO nanorods can adhere easily because of the seed layer on the substrate. We applied different experimental parameters to grow the ZnO seed layer and the ZnO NRs. To examine the experimental condition, ZnO nanorods with various structures can be observed by scanning electron microscope (SEM). In addition, we adjust the pH value in hydrothermal environment to observe the growth of ZnO nanorods. Furthermore, we perform X-ray diffraction (XRD),and energy dispersive X-ray spectroscopy (EDX) to monitor the material properties of the ZnO NRs.
