Influence of a Magnetic Field on the Structural and Morphological Properties of the Hydrothermal Growth of ZnO Nanostructure

The effect of a permanent magnetic field (500 Gauss) on the hydrothermal preparation of zinc oxide (ZnO) nanostructures was studied. Using this approach, ZnO was deposited on various substrates, including insulator/glass, semiconductor/silicon, and conductor/FTO-glass. A horizontal substrate position without and with the magnetic field (B=0G,andB=500 G) was investigated, respectively. The surface morphology and crystalline structure of the produced samples were characterised by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The main finding of this work was to assess improvement in crystal structure parameters and morphology enhancement by using magnetic fields.
