ZnO nanorod arrays were obtained on a silicon wafer coated with rutile TiO2 thin films by a hydrothermal method. They were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and selected area electron diffraction (SAED). The effect of the concentration of the solution was also investigated. The results reveal ZnO nanorods prepared in mixture of 0.025mol/L of Zn(NO3)2·6H2O and C6H12N4 at 70℃ for 4h are about 100nm in average diameter and about 1μm in length, which possess wurtzite structure with a c-axis growth orientation. The room temperature photoluminescence of the as-prepared ZnO films exhibits a strong UV emission at about 389 nm and a weak emission at about 466nm.
