Plasmon-Exciton Resonant Energy Transfer: Across Scales Hybrid Systems

Figure 15

(a) Sketch of the designed chip used as mold into PDMS. Purple area R represents the reservoir of NP solutions, whereas final part of the long microchannels ( = 11 cm) is used for ellipsometric investigations. (b) SEM image of a microchannel, showing the obtained crystal-like 3D assembly. White bar is 10 μm. (c) Zoom of image (b); scale bar is now 1 μm. (d) Three-dimensional sketch of the densely packed gain-functionalized Au NPs. (e) Variable Angle Pump-probe Ellipsometric setup (VAPE). External CW excitation source at  nm.
