Abstract
The structural and optical properties of ZnO-based nanostructure exhibit substratedependent variations. A comprehensive understanding of how different substrates influence the crystalline structure, absorbance and surface morphology of the deposited films remains a great challenge. This study was done to investigate the structural and optical properties of zinc oxide (ZnO) that alter with graphene oxide {GO) deposited on various substrates; glass, silicon, indium tin oxide (ITO) and polyethylene terephthalate (PET) by solution immersion method. The structural properties were studied using X-ray diltraction (XRD) and Fourier-transtorm intrared (FTIR). The optical properties of samples were determined using ultraviolet-visible (UV-VIS) spectroscopy and Raman spectroscopy. The XRD result revealed that all GO/ZnO samples have polycrystalline structures while FTIR showed the presence of C-O, C=O and C-H compounds on all substrates. The highest absorbance of 3.40 was shown by the GO/ZnO sample which was grown on a glass substrate while the lowest absorbance of 1.50 was exhibited by the sample that was grown on PET substrate. Based on the Raman spectrum all samples showed variety in phonon energy when ZnO was grown on different substrates.
