Abstract

The Zinc Oxide (ZnO) films were fabricated on glass coated with indium tin oxide (ITO) substrate by sol-gel spin coating technique. With regard to the preheating temperatures, the effects of growth mechanism ZnO films on the optical and structural properties were investigated. In this study, the preheating temperatures were varied from 250°C, 280°C, and 300°C. The X-ray diffraction (XRD) and ultraviolet-visible (UV-Vis) spectroscopy were used to examine the structural and optical properties of the ZnO films. The XRD results revealed that, the ZnO films are highly crystalline for all samples which are dominated by (002) peak orientation. Meanwhile, observation from optical results indicated that, the variation of transmittance spectra were turn out and it is proportional to the preheating temperatures used. Overall, we realized that the properties of the ZnO films in the sol-gel spin coating technique strongly depend on the preheating temperature and need to be considered as important factor to obtain the high-quality of the ZnO films.
