For instance, the bands provided by the screen define the characteristics of the detected SPR, thus the projection of the spectral radiances on the monochromatically scanned SPR landscapes show that one can expect for Au films a complete SPR vs. characteristic in the red band (Fig.2c) , while for the green band the dip of the SPR landscape is in one extreme of the covered illuminating angles and for the blue band is outside the CSPT range (Fig.2c).
