Zinc Oxide (ZnO) thin film has been synthesized using the chemical spray pyrolysis technique and ethylene glycol
has been used as solvent during the synthesis. X-ray diffraction (XRD) results show cubic and tetragonal phases
of ZnO and the grain size was calculated to be 2.57nm. Optical characterization reveals very high transmittance
within the visible-ultraviolet region and a bandgap of 3.49 eV was obtained for ZnO thin film. Scanning Electron
Microscopic (SEM) analysis showed a void-free non-homogenous surface.
Keywords: ZnO; Spray pyrolysis; Ethylene glycol; Grain size.
