| description | This study we don't use any catalyst or buffer layer before the reaction by hydrothermal method was used to prepare ZnO nano rods and flowerlike. The process has taken place inside Teflon lined stainless steel autoclave with volume 50 ml (homemade). ZnO nano rods and flowerlike were successfully synthesized using ZnO nanoparticles (20 nanometer) and NaOH (concentrations 3M) was the starting materials for the chemical reaction under stirring. The suspension was transferred into a Teflon lined sealed stainless steel autoclave and kept at 90 0C for 24 h,48 h and 72 h. The influence of the synthesis process on the morphology, the crystallinity and structural properties are studied by X-ray diffraction and field emission scanning electron microscope (FE-SEM), the experimental pattern of the films show that diffraction peaks can be assigned to the Wurtzite hexagonal-shaped ZnO as shown in the FE-SEM pictures, also the morphology of the films studied by atomic force microscope shows that the prepared thick films have high roughness specially for the powder prepared 46 h . |
