Abstract

Al-doped zinc oxide (ZnO: Al%) based on powders prepared via Polyol method is deposited on glass substrate by spin coating. Samples were annealed at 220°C, 295°C, and 370°C for 1 hour in ambient conditions. The effects of annealing and aluminum doping concentration (Al%) on the structural and optical properties of ZnO: Al% thin films are investigated by X-ray diffraction, AFM, and UV-Vis-IR spectroscopic techniques. The smallest crystallite size for ZnO: Al% is obtained with 0.6% doping owing to the formation of Al-O-Zn in the crystal lattice. The microstrain (ξ) decreases with the increasing TA which confirms the improvement of the crystalline quality of thin films. The AFM data are used to illustrate the surface morphology variation of thin films at different TA as well as Al% content. We also showed that the optical constants are considerably influenced by the Al% and TA. Photoluminescence spectra of ZnO: Al% powders analyzed based on Franck-Condon progression.

Keywords: Al-doped ZnO Thin Films; Polyol Method; X-ray Diffraction; Transmission; AFM
