In this study, Yttrium Ferrite based nano electroceramics were
prepared by the doping at various ratios of graphene oxide by the hydrothermal
method. The obtained doped and undoped samples were characterized by XRD, SEM,
FTIR, DTA, UV-VIS-NIR spectroscopy, temperature dependent electrical resistance
changes and dielectric measurements. From the XRD results, it is observed that
the obtained samples are polycrystalline with an Orthorhombic structure. The
crystal parameters are changed with the doping of graphene oxide. FTIR spectra
indicate that the graphene oxide changes the peak intensities. This confirms
the incorporation of the graphene oxide into the ceramic structure. The doping
of the graphene oxide changes the optical band gaps of the samples. The
dielectric constants of the samples are changed with the graphene oxide. The DC
electrical conductivity measurements confirm the semiconducting behavior of the
samples. The obtained results indicate that the electronic and nanostructure of
the synthesized electroceramics can be controlled by the doping of graphene oxide
for electronic and energy applications.
