Abstract
Flower-shaped ZnO nanocrystals have been synthesized by a two-step solution based deposition method; mist-atomizer and solution-immersion on seeded glass substrate. The samples are annealed at different temperature in the range of 350 to 500 ᵒC. The structural properties of the samples were studied. Field emission scanning electron microscopy (FESEM) micrograph and atomic force microscopy (AFM) images for the ZnO thin films were obtained. Morphological changes due to various annealing temperature are discussed as changes observed in the ZnO crystals. FESEM image of the surface of the ZnO reveal the flowerlike vertical nanorods with hexagonal crossection. The samples with higher roughness analyzed from AFM images indicate that the sample have larger grain. AFM results are found in good agreement and supported the FESEM results.
