a, b Transmission spectra in the visible (400–900 nm) and near-infra-red (900–1500 nm) ranges. The results for 6 samples with various numbers of PE bilayers are presented. Note the different scales along the x axis for (a) and (b). Shifts of maxima (c) and minima (d) of the transmission along with the linear fits
