Figure 2

Optical response of an optimized spherical core-shell nanoresonator containing a decentralized dipole. (a) Purcell factor i.e. total decay rate enhancement and quantum efficiency (b) radiative rate enhancement and scattering cross section spectra of the optimized configuration corresponding to the excitation (dashed lines) and emission (solid lines), inset: zoomed spectra around the excitation wavelength. (c) Distribution of the surface charge density in arbitrary units and the normalized E-field enhancement with respect to vacuum on logarithmic scale at the SiV excitation (top) and emission (bottom).
