In this study, zinc oxide nanorods (ZnO NRs) were prepared through chemical bath deposition using glass and fluorine-doped tin oxide (FTO) substrates, and their crystalline structure was investigated through X-ray diffraction. Results showed that the prepared ZnO NRs had wurtzite structure and grew along the [002] orientation, and ZnO NRs grown on the FTO substrate was more crystalline than those grown on the glass substrate. Field-emission scanning electron microscopy images showed that the glass sample had rod-like morphology and uniform distribution with 95 nm diameter and average length of approximately 980 nm, whereas the FTO-coated glass had 110 nm diameter and average length of approximately 1000 nm. The direct transition optica1 band gaps of the glass and FTO-coated glass samples were 3.28 and 3.97 eV, respectively.
