Nano electroceramic samples of Bismuth Ferrite/Graphene
Oxide were prepared by
the hydrothermal process. The crystalline structure,
morphological properties, electrical and optical properties of samples were investigated.
X-ray results
confirm that all the BFO nanopowders are
polycrystalline with a cubic structure. The
crystallite sizes and lattice parameters values of the samples
were calculated. SEM and TEM results indicate
that the Bismuth ferrite/Graphene oxide powders have nanostructure. The average
grain size values of the powders were found to be 351,
337, 411 and 371nm for BF0,
BFO20, BFO50 and BFO100 samples, respectively. The effects of the Graphene oxide
doped on the Bismuth ferrite are resulted in a change of grain size. The optical band gaps of the nano electroceramics were
calculated for the various amount of Graphene oxide. The optical constants of
the Bismuth Ferrite were changed with Graphene oxide doping. The room
temperature dielectric measurement with frequency reveals the dielectric
constant and loss are affected with increasing frequency for BFO nanoceramics. The
alternating current conductivity of the as-synthesized nano electroceramics
increases with the increasing frequency. The obtained results suggest that the
structural, optical and electrical properties of BFO can be controlled and
changed by Graphene Oxide doping.
