Comparative study on dielectric and structural properties of undoped, Mn-doped, and Ni-doped ZnO nanoparticles by impedance spectroscopy analysis

In this work, the results of the structural and dielectric investigation of pure, Mn-doped, and Ni-doped ZnO nanoparticles (NPs), which have been prepared by simple sol–gel method using zinc acetate as precursor, are studied. The synthesized samples are examined via XRD at 300 K, FE-SEM, FTIR, and μ Autolab/FRA2 impedance spectroscopy techniques. XRD results and calculated lattice parameters of all synthesized samples have revealed that...
