Figure 7

Calculated charge distribution on the surface of a GNR@SiO2 excited by a green-emission dipole in position L (a, b) and position T (c, d). The dipoles are oriented either parallel a, d or perpendicular b, c to the orientation of the transverse plasmonic dipole of the GNR. Note that the green-emission dipole orientation is represented by enlarged black arrows and the nature of the induced charge configurations is labeled by +/− signs.
