Zinc oxide (ZnO) thin films were deposited on glass substrates by spray pyrolysis technique by decomposition of zinc acetate dihydrate in ethanol. The ZnO thin films were deposited at 350°C and annealed at 500°C for 2 h. The substrate was R217102 glass in a size of 30 cm × 7.5 cm × 0.1 cm. The films exhibited a hexagonal wurtzite structure with a strong (002) preferred orientation. The higher value of crystallite size (20.29 nm) was attained with films annealed at 500°C, probably due to improvement of the crystallinity of the films with heating. The average transmittance of the films, by UV-Vis, was over of 95 %. The band gap energy varied from 3.279 to 3.288 eV for the non-annealed and annealed films, respectively. The electrical resistivity was measured to be 0.4 Ω.cm. |
