Effect of growth thickness on the morphology and characteristics of ZnO nanorods were discussed. The photoluminescence and transmittance of the ZnO nanorods were measured by UV-VIS spectrophotometer and fluorescence spectrophotometer. The scanning electron microscope (SEM) results showed when the thickness increased, the diameters of the nanorods increased. The XRD results found that the ZnO nanorods had monocrystalline structure. The photoluminescence measurements showed that the ZnO nanostructures had good ultraviolet emission and blue emission. Raman scattering spectrum was used to measure substance structure of the ZnO nanostructure. We assembled the top electrode for nanogenerator with ZnO nanorods and measured its micro-current driven by ultrasonic waves. 關鍵字： (ZnO) (Nanorod) (liquid solution epitaxial method) (Phot
