چکیده

Abstract This experiment addressed the effect of Nickel-doped on dielectric, ac conductivity, and optical properties pure doped Zn (1−x) Ni x O (x = 0, 3 6%) nanostructures. The un-doped Ni-doped ZnO nanostructures were synthesized using co-precipitation. In this paper, frequency-dependent dielectric electrical conductivity examined at various temperatures ranging from 320 K to 460 an LCR meter. For morphological investigation, prepared samples analyzed field emission-scanning electron microscopy (FE-SEM), UV visible Spectroscopy was used room temperature. constant ( ε ′ ), loss ^{\prime\prime} accent="false">″ tangent (tan δ real as well imaginary part impedance against frequency 100 Hz 2 × 10 6 that declines with increases in different 320–460 K.
