It is prepared by decomposition of silver nitrate solution through Sodium Hydroxide route. The particle size and the nature of the crystal are characterized by X-Ray Diffraction (XRD). The surface morphology of the samples is studied by Scanning Electron Microscope (SEM). The SEM image indicates that the particles are uniformly spread and shape of the particles is semi-spherical in nature. The XRD shows that the peaks are highly intense. It shows that the particles are highly crystalline. The sizes of the particles were calculated by Debye Scherrer formula from the values of Full Width Half Maximum (FWHM), calculated from the peaks. The sizes of silver oxide and silver were obtained to be 25.75 nm and 52 nm respectively. The size of Silver is high because of coalescence of the particle due to annealing effect.
