Abstract

Abstract Cobalt oxide/zinc oxide core/shell nanoparticles (CZ NPs) were synthesized at low temperature by the sol–gel method. X-ray diffraction (XRD) was used for the detection of crystalline phases. Energy-dispersive analysis X-ray (EDAX) results for the sample as prepared showed that where only Co, Zn, C, and O was found, in forming CZ core/shell NPs. Transmission electron microscopy images indicated that the particles size of core/shell sample CZ NPs and the particles size were around 12 nm. The optical properties study by UV–Vis spectroscopy to estimate the bandgap of core/shell NPs. Frequency dependence dielectric was observed in core/shell NPs were prepared using the sol–gel method. Dielectric constant ε ′ and dielectric loss ε ″ for CZ NPs were found to decrease with increasing frequency. Graphical abstract
