a, b The far-field angular distributions for the HMM1 and HMM2, respectively. c The scattering efficiency (marked as the red color) and the mode volume (marked as the blue color) of the PNCs on top of the HMM1 and HMM2 substrates. Purcell factors for a perpendicular dipole emitter placed on top of the d HMM1 and e HMM2 substrates. The dipole-HMM separation distance was varied from 1 to 30 nm. f The local density of states (ρp) (marked as the red color) and the spontaneous decay rate (γ) (marked as the blue color) were calculated by the method of dyadic Green’s function. The simulated spectra cover the wavelength range from 400 to 700 nm.
