ZnO nanostructures: analysis and characterization by the electrospinning technique

The electrospinning technique has been employed to synthesize ZnO nanostructures. The significant characterization and analysis of grain and crystallite sizes have been inspected by scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray diffraction (XRD) that are unequivocally influenced by varying the flow rates of solution precursor: 2, 4, and 6 8 μL/min. Meanwhile, the flow rate could affect the morphology and topography of ZnO nanostructures. The optical properties of photoluminescence (PL) are investigated. The bulk modulus, refractive index, and optical dielectric constant are calculated using specific empirical models to verify the experimental results.
