Abstract
We present here structural, mechanical, and electrical properties at different values of temperatures (30–150 °C) for Zn1-xAgxO nanoparticles (NPs) with x = 0.00, 0.02, and 0.04. All NPs samples show wurtzite structure, tensile stress, and brittle character. Ag doping resulted in a slight increase in crystallite size, along with reduction in dislocation density, micro-strain, specific surface area, porosity, particle size, and M–O spacing. The FTIR spectra exhibit various bands between 3450.69 and 411.3 cm−1 for all samples, with most shifting to lower wavenumbers as x increases. With increasing Ag doping content up to 0.04, the Debye temperature, effective mass, elastic moduli, hardness, and wave velocities all gradually increased. The dielectric constant, dielectric loss, AC conductivity, and F-factor increase with increasing temperature (T) or doping content (x). In addition, the activation energy of the charge carriers, determined using the Arrhenius equation, decreased with increasing x or f, ranging from 0.187 to 0.68 eV across all samples. In general, no relaxation peaks are observed in the tan δ curves for x = 0.00 and x = 0.02 across the entire temperature range; ...
