The properties of zinc oxide with graphene oxide on different substrate / Nik Nur Syakira Mohd Rodzi

In this research, the structural and optical properties of Graphene Oxide (GO)
with Zinc Oxide (ZnO) thin film were successfully deposited on various
substrates including glass, silicon, indium tin oxide (ITO) and polyethylene
terephthalate (PET) by solution immersion method. In this project, the structural
and optical properties of the samples were studied by using X-ray diffraction
(XRD), Fourier-Transform Infrared (FTIR) Spectroscopy, Ultraviolet-Visible
(UV-VIS) Spectroscopy and Raman Spectroscopy. The XRD result revealed that
the samples have a wurtzite structure as the peaks dominated by ZnO (0 0 2). The
presence of C-O, C=O and C-H compounds on all substrates on FTIR
spectroscopy contributes to the GO peak. The highest absorbance of GO/ZnO
thin film samples is observed for ITO substrate while the lowest absorbance of
GO/ZnO thin film is PET substrate. Last but not least, Raman scattering findings
observed that all the samples have a high crystalline quality of the produced GO
with ZnO thin films on various substrates.
