Tuned NV emission.
(a) Variation of the NV spectra for different reverse bias potentials (measured on spot 1 depicted in Fig. 3a). Each spectrum was normalized to the amplitude of the first order Raman line to allow comparison and evaluation. (b) Reference spectrum (normalized to the first order Raman line) measured on spot 2 as depicted in Fig. 3a. (c) Background corrected variations of the spectra shown in (a) with the amplitudes normalized to the maximum amplitude. (d) Relative change of the integrated intensities of the NV0 and NV− amplitudes in (c) for different bias-voltages applied.
