SOL- GEL DIP-COATED NANOSTRUCTURED ZNO THIN FILMS: EFFECT OF COATING AND PH ON PARTICLE SIZE

Nanostructured ZnO thin films were prepared by sol-gel dip coating technique. Zinc acetate and ammonium hydroxide were used as precursors and ethanol was as solvent. Different numbers of coating cycle were employed to obtain the films with varying thicknesses. These films were annealed at 5000C and were characterized by x-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive analysis of x-rays (EDAX). The results are discussed.
