23. Treatment of optical spectra at interfaces is a nontrivial task, but many phenomena can be approximated by assuming a homogeneous medium with an effective refractive index. Here, we set n = 1.35 as in ref 12, where the surrounding index was determined by fitting the GNP plasmon spectrum in that experiment.

25. For dipole moments perfectly perpendicular to the interface, a quantum efficiency of 0.95 is reduced to 0.67. Since our bor-FDTD calculations of the decay rates in Figure 3b assume such molecules, the results of the fluorescence enhancement are slightly overestimated.
