We investigated the effect of an annealed ZnO buffer layer on the structural and optical properties of hydrothermally grown ZnO nanorods. ZnO buffer layers were deposited on a p-type Si(100) substrate by radio-frequency (RF) sputtering. ZnO nanorods were grown on as-deposited and annealed ZnO buffer layers by a hydrothermal process at a low temperature for various growth times. Annealed ZnO buffer layers have higher $c$-axis texturing than as-deposited ZnO buffer layer. ZnO nanorods grown on annealed ZnO buffer layers had higher X-ray diffraction (002) peak intensities and ultraviolet (UV) emission intensities than those grown on the as-deposited ZnO buffer layer. The degree of $c$-axis texturing of ZnO buffer layer affects the perpendicular growth for hydrothermal ZnO nanorod.
