Model for cold-coated NAA samples and comparison of the measured and the best least-squares fitting simulated reflectance spectra. (a) Schematic drawing of the proposed theoretical model for gold-coated NAA samples. Red symbols joined with solid red line represent experimentally measured reflectance spectra. Solid black line represents best least-square fit corresponding to simulation. Plots on the left correspond to the UV–vis spectral region, while plots on the right correspond to the near-IR spectral region. (b, c) tPW = 0 min and (d, e) tPW = 18 min.
