Studying the effect of concentration of solutions on the properties of nickel oxide nanoparticles

In this study, copper doping concentrations of 0.02 and 0.04 were employed to create (NiO) films, which were then subjected to optical and structural tests, including X-ray diffraction, atomic force microscopy, and absorbance, reflectivity, and energy gap. The higher doping ratio resulted in a smaller value for the granular size by (62nm), whereas the pure films gave a granular size of (118nm), and this result agreed with the results of the XRD. The doping ratios did not affect the phase of the prepared films, but they did affect both the granular size and the specific surface area. The range of particle sizes used for the AFM analysis. According to the findings of the eye examinations, the absorbance and reflectivity increased with the amount of doping while the transmittance decreased. The membrane had an energy gap of 1.65 eV during the time when the pure membrane had an energy gap of 0.04Cu, but the energy gap shrinks as the amount of cu in the thin film grows (1.85 eV).
