Synthesis, Impedance and Current-Voltage Spectroscopic Characterization of Novel Gadolinium Titanate Nano Structures

Gadolinium (Gd) doped titanate nanostructures (NS) with a new set of 10-50 wt. % of Gd were synthesized by microwave-assisted hydrothermal and reduction using hydrazine hydrate. The crystal structure has been evaluated with SEM (scanning electron microscopy) analysis exhibited rod like geometry of nanoparticles (NPs). XRD (X-ray diffraction spectroscopy) analysis of GdTiO₃ and undoped titanate nanostructure (NS) intense peak exhibited crystal tetragonal structure. CV (cyclic voltammetry) exhibited an oxidation potential of 50 wt. % of GdTiO₃ was found to be - 0.54 eV. UV-Visible spectroscopic revealed absorptivity of 50 wt. % of GdTiO₃ was found to be 650 nm (visible region) and undoped titanate absorptivity at 320 nm (UV region). The pelletized nanostructures of GdTiO₃ were investigated for current-voltage (I-V), capacitance-voltage (C-V), resistance-voltage (R-V) measurements, which showed frequency range in between 1 kHz to 2 MHz and 50 wt
