Abstract: Zinc oxide (ZnO) films were prepared by the sol-dipping coating method on conductive glass (FTO) substrates. The effects of the aging time and the calcining temperature on the structure, morphology, transmittance properties of the films were investigated by X -ray diffraction (XRD), field emission scanning electron microscope (SEM), and ultraviolet spectrophotometer (UV). The results showed that when the aging time was 26h and the calcining temperature was 550℃, ZnO films with the lower defect-density were composed of stout prismatic particles and possessed higher transmission.

Key words: sol-dipping coating; ZnO film; calcining temperature; aging time
