Abstract

Undoped ZnO thin films were prepared by sol gel method and deposited on ITO substrate using dip-coating technique. The effects of annealing treatment on structural and optical properties were investigated. The starting material was zinc acetate dihydrate, 2-methoxyethanol was used as solvent and monoethanolamine (MEA) as stabilizer. Structural and optical measurements show an important effect of annealing treatment on texture, grain sizes, strains, band gap and refractive index. Annealing at 600°C gives the best structural and optical properties of ZnO thin films..
