Abstract

In this paper, stearic acid/Zn2+monolayer were formed at air–water interface and then multilayers were deposited onto a glass slide by Langmuir–Blodgett method. After annealing at 300°C for 0.25 h and 550°C for 2 h,ZnOthin films were fabricated. The optimized parameters for monolayer formation and multilayers deposition were determined by the surface pressure-surface area (Π-A) isotherm and transfer ratio (t.r.), respectively. The results of X-ray diffraction showed that multilayers changed intoZnOthin films with hexagonal structure and of high crystallization after annealing at high temperature. The observation of SEM images indicated thatZnOthin films had a uniform and flat surface with compact arrangement.
