One-dimensional (1-D) ZnO nanorods with different aspect ratios (length to diameter) were prepared by a direct solvothermal method using octanol as a solvent. We investigated the concentration effect of Zn precursor for the manipulation of aspect ratio of ZnO nanorods. Morphological and structural characterizations were carried out by X-ray diffraction and transmission electron microscopy. As-obtained ZnO nanorods were determined to be a single crystalline nature with their c-axis as the primary growth direction. UV-Vis and photoluminescence spectra of ZnO nanorods exhibited a red-shift of UV absorption from 347 to 356 nm and a blue-shift of UV emission from 393 to 388 nm, respectively. A good crystallinity of ZnO nanorods was demonstrated with a strong UV emission together with a weak and broad green emission band from 528 to 552 nm, which is typically attributed to the oxygen defects.
