Abstract- Zinc oxide coating was grown using on Si(111) by electrodeposition. Crystalline structure,optical and morphological properties were studied using X-ray diffraction (XRD), reflectance spectrum and scanning electron microscopy (SEM), respectively.Hexa-gonal wurtzite nanocrystalline structure was grown with random orientation. Surface morphology shows the effect of deposition time on shape and size of grown structures. As deposition time increase, the formed structure stretched in one dimension, furthermore, three-dimensional growth overwhelms. The quantum confinement effect and band filling have been discussed on optical band gap widening from 3.21eV to 3.70eV.
