Abstract: We used the co-precipitation method to create pure phase Zinc Oxide nanostructures in this study. X-ray diffraction was used to investigate the phase and scale of synthesised nanostructures (XRD). The ZnO sample calcined at 400 °C has a crystalline size of 36.1 nm, an inter planner spacing of 2.7010 Å, and a volume of 71.62 Å3. The morphological research was done using a scanning electron microscope (SEM). The IR peaks near around 510 cm-1 correspond to stretching of the Zn-O bonds, according to IR studies conducted with an FTIR spectrometer. A kaithely source metre was used to measure the current-voltage characteristics and resistivity of zinc oxide nanostructures. Impedance spectroscopy of synthesised samples was performed at room temperature using a galvinostat with an applied voltage of 120 mV and a frequency range of 50 Hz to 5 MHz. For ZnO calcined at 400°C, the grain boundary resistance is about 32 MΩ (at 310 K).

Keywords: Zinc Oxide, X-RD, SEM, FTIR, AC Impedance Spectroscopy.
