Zinc oxide Nanorods (ZnO-NRs) were deposited onto glass substrates using zinc chloride by Ultrasonic Spray Pyrolysis (USP) method. The films were prepared in different deposition time at optimum deposition parameters. The effect of deposition time on the structural, morphological and optical properties of ZnO-NRs was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis spectrometry (UV-Vis). XRD and SEM measurements indicated that all films show a hexagonal wurtzite Nano rods (NRs) structure growing preferentially along c-axis perpendicular to the surface of the substrate. Optical transmission spectra showed high transmittance of 80-85% in the visible range for all thin films, and increase of optical band gap from 3.24 to 3.265 eV with deposition time. The high quality c-axis orientated ZnO thin films with minimum strain and tuneable optical properties could be used as a transparent conducting oxide (TCO) for optoelectronic applications.

In this paper, ZnO nanofilms are prepared on quartz substrate by ultrasonic spray pyrolysis (USP) technology. The effects of substrate temperature and deposition time on the micro-structural, morphological and optical properties of ZnO thin films are investigated in detail. Measurements indicate that the growth process of the film is as follows: Micro grains accumulation [Formula: see text] grains’ expansion [Formula: see text] grow into certain nanostructures under different temperature. Nanostructures of the film are as follows: Irregular broken hexagonal-like structure ([Formula: see text]C); coexisting of broken hexagonal- and sheet-like structure (450–500[Formula: see text]C); regular closed packed sheets-like structure ([Formula: see text]C). In addition, all results show that RMS roughness of the films is less than 20 nm. Moreover, the visible transmittance of these samples is higher than 90%. Which display that ZnO films with low roughness and excellent optical properties can be also fabricated by low-cost USP method.
