Abstract

In this study, zinc oxide nano-sheets were prepared via the sol-gel method using zinc nitrate as the precursor salt, that pure and doped zinc oxide nanostructure synthesized with cheap materials and using an easy and available method with low laboratory equipment and in a very short period of time. Subsequently, the samples doped with iron and copper impurities. The structural and morphological properties of the prepared samples determined using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and Fourier-transform infrared spectroscopy (FT-IR). The XRD results indicated that the zinc oxide nanoparticles in all samples adopted a wurtzite crystal structure with no any additional peaks observed. The functional groups and chemical interactions of the zinc oxide samples also determined at various peaks using FT-IR data, confirming the presence of Zn-O bonds in the samples as observed by XRD. The analysis of FESEM revealed that the impurities led to the formation of different morphologies for each sample. It can conclude that the type of impurities influences the morphological changes while the structure remains unchanged. To investigate the band-gap, UV-Visible spectroscopy employed, showing a decrease in the band-gap of the samples with increasing impurities.
