Silver oxide (Ag₂O) nanoparticles were synthesized using a wet chemical technique. The synthesized nanoparticles were investigated by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV analysis and dielectric studies. The powder X-ray diffraction (XRD) shows that facecentered cube structure of silver oxide and the average crystallite sizes were calculated to be 18.6 nm. The particle size and morphology were studied using the scanning electron microscope (SEM) and transmission electron microscopy (TEM). The UV-Visible absorption spectrum analyzing showed the strong absorption peak and nearly transparent nature of the particle at visible region. The wide range of band gap energy value was found to be 4.70 eV. The dielectric properties of silver oxide nanoparticles were studied in the frequency range of 50 Hz–5 MHz at different temperatures. The frequency dependence of the dielectric constant and dielectric loss is found to decrease with an increase in the frequency at different temperatures. Further, electronic properties, such as valence electron plasma energy, average energy gap or Penn gap, Fermi energy and electronic polarizability of the silver oxide nanoparticles were calculated. AC electrical conductivity measurement was studied.
