Effect of deposition parameters on the structural properties of ZnO nanopowders prepared by microwave-assisted hydrothermal synthesis
چکیده انگلیسی


• ZnO nanopowders were synthesized via microwave-assisted hydrothermal method.
• The effects of pH and microwave irradiation times on the crystalline structure of the ZnO have been investigated by XRD.
• The crystalline quality of ZnO nanopowders increased with increasing pH value.
• Microwave irradiation time and pH value showed a significant effect on the surface morphology.

ZnO nanopowders were synthesized via microwave-assisted hydrothermal method at different deposition (microwave irradiation) times and pH values. The effects of pH and deposition (microwave irradiation) time on the crystalline structure and orientation of the ZnO nanopowders have been investigated by X-ray diffraction (XRD) study. XRD observations showed that the crystalline quality of ZnO nanopowders increased with increasing pH value. The crystallite size and texture coefficient values of ZnO nanopowders were calculated. The structural quality of ZnO nanopowder was improved by deposition parameters. Field emission scanning electron microscope (FESEM) was used to analyze the surface morphology of the ZnO nanopowders. Microwave irradiation time and pH value showed a significant effect on the surface morphology.
