This research presents a facile one step aqueous chemical route (ACR) for synthetizing and depositing Sn-doped titanium dioxide (TiO2) nanorod arrays (TNAs) on a transparent conductive oxide (TCO) glass substrate. The prepared sample was annealed at 450 °C for 2 hours. The effect of Sn doping on structural property of TNAs has been investigated with FESEM, EDX and XRD. The EDX analysis shows the existence of titanium, oxygen, and tin in the deposited Sn-doped TNAs (STO) sample. The surface morphology result shows that the average diameter of the prepared Sn-doped TNAs was decreased compared to undoped TNAs. Furthermore, the XRD analysis reveals that the deposited STO showed a rutile structure. STO exhibits smaller crystallite size, strain, lattice mismatch, and lattice parameters than the undoped TNAs sample. Thus, we conclude that the structural property of TNAs can be tuned by Sn doping using our introduced method. © 2018 Author(s).
