Pure and cerium oxide (CeO2)-doped zinc oxide (ZnO) rods have been successfully grown on glass substrates using hydrothermal method. Growth of ZnO nanorods has two main processes, i.e. deposition of seed layer and growth of rods. The concentration ratios of Ce/ZnO are of about 1%, 5%, and 10%. The effect of CeO2 dopan on the structural and morphology of ZnO nanorods were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersion X-ray (EDX), and Fourier transform infrared (FTIR). The XRD spektrum on pure and CeO2-doped ZnO rods have hexagonal wurtzite structure with three highest peaks on the lattice of (100), (002), and (101), and face-centered cubic CeO2 phase on the lattice of (111) and (200). Analysis result of SEM confirmed that pure and CeO2-doped ZnO rods formed agglomeration of hexagonal flower-like rods. The addition of CeO2 shifted ZnO peaks of FTIR spectrum from 729 cm-1 to ~780 cm-1 .
