摘要：

In this present study, the ZnO nanorods were synthesized by using the hydrothermal method with various precursor concentrations. The ZnO nanorods were characterized by XRay Diffractometer (XRD) to identify the crystal structure, Scanning Electron Microscopy (SEM) to determine the morphology, and UV- Vis Spectrophotometer to determine the band gap. It was shown that the ZnO nanorods have hexagonal wurtzite crystal structure with the caxis orientation at (002) Bragg's plane. The morphology of the ZnO particles was in a rod structure growing over the surface of the substrate. The diameter of the ZnO nanorods resulted ifrom the concentrations of 30, 35 mM, and 45 mM were 94.2, 156.3, and 76.7 nm, respectively. The data analysis of the UV- Vis data showed that the band gap of ZnO nanorods (similar to 3.18 eV) was smaller than that of ZnO nanoparticles (similar to 3.46 eV).
