a XRD pattern resulting from the characterization of a film produced from colloidal samples containing Ag@Silica NPs and b zoom of the same pattern, which shows fitting curves used to determine de parameters of the peaks. The samples were prepared using a laser pulse energy of 15 mJ, λ = 532 nm, f = 20 Hz, t = 20 min, and (1.25 × 10–4 M) of AgNO3
