Well-aligned ZnO nanorod arrays on Chaleted Sol-Gel-Derived ZnO thin films was achieved at a temperature of 90°C by a surfactant-assisted soft chemical approach. The nanorod arrays were characterized by XRD, SEM, XPS, and UV-Vis absorbance spectra. The ZnO nanorod arrays are wurtzite crystal stuctures preferentially orienting in the direction of the c-axis and ZnO nanorods are grown verticallyon the substrate. The XPS analysis shows the Zn:O ratio of ZnO nanorod arrays near is 1:1. The UV-Vis absorbance spectra indicate that ZnO nanorod arrays have absorption of visible-light as well as ultraviolet-light. Therefore, the ZnO nanorods may be good candidates for visible-light photocatalysis materials from the viewpoint of practical applications.

The Sn-doped ZnO thin films were deposited on glass and ITO by sol gel Spin Coating technique. The Structural and electrical properties of Sn-doped ZnO thin films were studied and discussed. The Sn-doped ZnO thin film particle sizes were decreased whenever the doping concentration increased. Besides that, the resistivity 7.7 x 102 Ω.cm was obtained at 2 at.% Sn-doped thin films and aligned ZnO nanorod arrays with large surface area were grown on 2 at.% Sn-doped ZnO film. Therefore, dye sensitized solar cell at 2.0 at.% Sn-doped ZnO thin films with aligned ZnO Nanorod arrays have improved in the photocurrent density and conversion efficiency.

Aligned ZnO Nanorod arrays are deposited on the Sn-doped ZnO thin film via sonicated sol-gel immersion method. The structural, optical, and electrical properties of the Sn-doped ZnO thin films were investigated. Results show that the Sn-doped ZnO thin films with small grain size (~20 nm), high average transmittance (96%) in visible region, and good resistivity7.7 × 102 Ω·cm are obtained for 2 at.% Sn doping concentration. The aligned ZnO nanorod arrays with large surface area were also obtained for 2 at.% Sn-doped ZnO thin film. They were grown on sol-gel derived Sn-doped ZnO thin film, which acts as a seed layer, via sonicated sol-gel immersion method. The grown aligned ZnO nanorod arrays show high transmittance at visible region. The fabricated dye-sensitised solar cell based on the 2.0 at.% Sn-doped ZnO thin film with aligned ZnO nanorod arrays exhibits improved current density, open-circuit voltage, fill factor, and conversion efficiency compared with the undoped ZnO and 1 at.% Sn-doped ZnO thin films.

Lithium-doped zinc oxide(ZLO) thin films were deposited on glass substrates by sol-gel method.And then by controlling processing parameters such as the amount of doped lithium and stability, etc,Well-aligned ZLO nanorod arrays were successfully grown on substrates by hydrothermal method, where the substrates were spin-coated with seed layer.The experiments show the 5% Li-doped and diameter of about 50nm of ZLO thin films nanorod arrays has the best performance photoluminescence and surfactants can promote the growth of ZLO rod-like nano-structures and contribute to the formation of ZLO nanorod arrays with highly oriented.
