Abstract
Metal oxide nanomaterials are very popular due to its extensive band gap with significant applications in photovoltaic, catalysis, sensors, actuators and many more. This work on the impact of Fe3+ ion substitution on structural and electronic transportation character of ZnO nano structures prepared through co-precipitation method. The prepared samples were characterized via XRD, Field Emission Scanning Electron Microscope, FT-IR (Infrared Spectroscopy), PL (Photo-luminescence) and Complex Impedance Spectroscopy. From the XRD data, the wurtzite hexagonal structure in space group P63mc was demonstrated. The calculated crystallite sizes, planner distance and cell volume of Fe/ZnO-300 nanoparticles is 28.6 nm, 2.6012 Å and 59.41 Å3. The micrograph of Morphologies reveals the agglomeration in samples. The PL spectrum traced via PL spectrometer with 320 nm excitation wavelength (λ). IR spectrums with acmes close to 529–634 cm−1 were traced via FTIR technique and ensuing to stretching in the Zn-O bond. The impedance spectroscopies of La/ZnO-300 nanoparticles were measured via impedance Analyzer in the frequency assortment 5 MHz to 10 Hz at room temperature (RT). The value of grain margin resistance is 26.10 MΩ (at 300 K or RT) with the dielectric constant value 370 for La/ZnO-300 samples.
