A simple and direct method has been developed to grow zinc oxide (ZnO) nanorods (NRs) on a fluorine-doped tin oxide-coated glass (FTO) substrate. Firstly, spray pyrolysis deposition method is applied followed by dipping the substrate in a solution of ZnO growth reagents. The morphology, structure, and optical properties of the obtained thin film are investigated. The results demonstrate the successful synthesis of the ZnO NRs on FTO substrate. The NRs have a hexagonal rod like structure with diameter and length of 240 nm and 670 nm, respectively. FTO/ZnO NRs exhibited absorption of UV wavelengths and high transmittance in visible light region, with energy bandgap (E g ) of 3.2 eV. The characteristics of the FTO/ZnO NRs film can be explored in photovoltaic applications such as dye-sensitized solar cells.

“…Although numerous preparation techniques including sol-gel [7], electrodeposition [8], hydrothermal [9], chemical bath deposition (CBD) [10], solvothermal synthesis [11], RF sputtering [12], glaze firing [13], reactive sputtering [14], and many others are considered adequate to produce ZnO in its intended thin film forms, the spray pyrolysis in particular has received recently adequate attention because of its simplicity, economics, and ease of scale up for large scale production [15][16][17][18][19][20]. In addition, the spray pyrolysis method can be easily altered to produce films of different morphologies including nano-sheets, -wires, -combs, -flowers, and -rods [6].…”

Micro structured zinc oxide (ZnO) is of potential use in solar cells, solid state gas sensors, and other optoelectronic devices. For the advancement of these technologies, a comprehensive understanding of these materials' optical characteristics is considered essential. Using the spray pyrolysis (SP) method, thin films of ZnO micro rods are deposited from aqueous zinc chloride solution on silicon substrates held at 350±5 °C. The films have been studied using the data acquired from the X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), reflectance and photoluminescence (PL) spectroscopy. Hence, the XRD and SEM confirmed the films' hexagonal phase and revealed the tapered ends of the hexagonal rods. The optical parameters including the refractive index, extinction coefficient, absorption coefficient, real and imaginary dielectric constants, conductivity, and the energy loss are all deduced from the reflectance spectra. Finally, the photoluminescence spectra of the studied samples are measured at room temperature using two excitation wavelengths: 300 and 365nm. As such, the obtained results confirmed the quality of the prepared films and allowed proper determination of their respective optical characteristics.
