Abstract

ZnO nanostructures are synthesised by hydrothermal method from zinc acetate dihydrate (Zn(CH3COO)2.2H2O) using water as a solvent. NaOH solution in water is used to adjust the pH of the growth solution. The ZnO nanostructures are synthesised from solution with pH varying from 7 to 12. The structural, morphology, and optical properties of the grown ZnO nanostructures are characterized by XRD, FESEM, EDS, UV-vis and photoluminescence spectroscopy. The growth of hexagonal shaped nanocrystals is observed at pH value of 7 and as the pH of the growth solution is increased the morphology of the nanomaterials changes from hexagonal rod shapes to hexagonal platelet shapes.
