摘要：
In this paper, ZnO nano-crystalline films were synthesized onto hot glass substrates by ultrasonic spray pyrolysis technique. The solution contains zinc acetate dihydrate (ZnC4H6O4 center dot 2H(2)O) mixed with methanol. The influence of the solution flow rate on the properties of ZnO was investigated. All films deposited were characterized by various techniques such as X-ray diffraction to determine the films structure, the scanning electron microscopy (SEM) for the morphology of the surfaces and UV-visible spectroscopy to determine the optical proprieties. The results show that ZnO nano-crystalline films have a hexagonal structure at type wurtzite. The crystallite size was varied between 36.79 and 20.11 nm, the optical transmission around 80% in visible rang and the optical band gap is varied from 3.274 to 3.282 eV. (C) 2015 Elsevier GmbH.
