摘要

This study investigates different rinsing processes using a successive ionic layer adsorption and reaction (SILAR) method to deposit ZnO thin films. Rinsing in ultrasonic-assisted deionized (DI) water reveals thin films with better adsorptive attraction compared with a traditional SILAR method because the former can remove the loosely attached ZnO and unreacted Zn (OH)2 grains. In this case, the ZnO films appear as large pellets and white particles with low transparency. The structure and transparency of ZnO thin films can be significantly improved by using ultrasonic irradiation and rinsing in ethylene glycol rather than rinsing in DI water. The obtained ZnO films exhibited were more smooth, compact, and diaphanous, and the transparencies of ZnO films reached as high as 90% in the visible-light wavelength region. Furthermore, when the rinsing temperature of ethylene glycol was increased from 95 to 125°C, the ZnO films appeared to have finer grain size, higher transparency, and lower oxygen vacancies. Mechanism analysis indicated that the ethylene glycol acts as a dispersing agent to reduce ZnO agglomeration and the higher rinsing temperature enhances the decomposition capability of Zn (OH)2.
