“…The HuangRys factor is 3.7 with only 2.7 percent of the transition strength being associated with the zero-phonon transition [35]. At high excitation densities there can be photoionization of the N-V center of interest and the creation of the neutrally charged [N-V] 0 center [36,37]. This center has a zero-phonon line at 575 nm with a vibronic band to lower energy [38].…”

Symmetry considerations are used in presenting a model of the electronic structure and the associated dynamics of the nitrogen-vacancy center in diamond. The model accounts for the occurrence of optically induced spin polarization, for the change of emission level with spin polarization and for new measurements of transient emission. The rate constants given are in variance to those reported previously.

As a potential candidate for quantum computation and metrology, the nitrogen vacancy (NV) center in diamond presents both challenges and opportunities resulting from charge-state conversion. By utilizing different lasers for the photon-induced charge-state conversion, we achieved subdiffraction charge-state manipulation. The charge-state depletion (CSD) microscopy resolution was improved to 4.1 nm by optimizing the laser pulse sequences. Subsequently, the electron spin-state dynamics of adjacent NV centers were selectively detected via the CSD. The experimental results demonstrated that the CSD can improve the spatial resolution of the measurement of NV centers for nanoscale sensing and quantum information. Keywords: charge state; NV center; photon ionization; super-resolution microscopy INTRODUCTION Because of the stable fluorescence and long coherence time of its spin state, the negatively charged nitrogen vacancy (NV 2 ) center in diamond has been studied extensively over the past decade. This defect has the potential to be used for quantum computation, 1-4 nanoscale metrology 5-8 and biological imaging. [9][10][11] To further extend the study of the interaction between a multi-NV center and the nanoscale sensing with the NV center, it is necessary to detect and control the NV center spin-state dynamics with high spatial resolution. 7,12-14 Therefore, many optical super-resolution microscopy techniques have been developed to detect single NV centers. [13][14][15][16][17] Among these methods, stimulated emission depletion (STED) microscopy 12,18-20 is one of the most promising. This method utilizes a doughnut-shaped laser to produce the position-dependent stimulated emission, which changes the fluorescence signal. With STED, the electron spin resonance signals of NV centers have been detected with a resolution lower than the diffraction limit. 12,21,22 A new super-resolution microscopy technique was recently developed by Han et al. 15 The authors replaced the stimulated excitation of STED with the dark-state pumping of NV centers. The dark state was later proven to be the neutral charge NV center (NV 0 ) by other groups. [23][24][25] The charge-state conversion results in a change of the local field in diamond 26 and the spectral diffusion of the NV center. 24,27 For high-fidelity quantum manipulation, the charge state should be well controlled. 28 Based on the mechanism of charge-state conversion and super-resolution microscopy, 25,29,30 we demonstrated the optical manipulation of the charge state of an NV center with subdiffraction resolution.

“…Blinking was observed in 25% of the luminescent sites. The 'off' state was at the level of the background signal, and blinking due to photochromism 16 was ruled out as the neutral NV luminescence signature was never observed in the spectra. Photobleaching was also observed on some of the centres; however, those analysed in this Letter showed luminescence over several hours of illumination.…”

Nitrogen-vacancy colour centres in diamond can undergo strong, spin-sensitive optical transitions under ambient conditions, which makes them attractive for applications in quantum optics 1 , nanoscale magnetometry 2,3 and biolabelling 4 . Although nitrogen-vacancy centres have been observed in aggregated detonation nanodiamonds 5 and milled nanodiamonds 6 , they have not been observed in very small isolated nanodiamonds 7 . Here, we report the first direct observation of nitrogen-vacancy centres in discrete 5-nm nanodiamonds at room temperature, including evidence for intermittency in the luminescence (blinking) from the nanodiamonds. We also show that it is possible to control this blinking by modifying the surface of the nanodiamonds.Detonation nanodiamond is routinely produced on an industrial scale, and the raw material can be disintegrated into a stable 5-nm monodisperse colloid 8 . The combination of inert core and chemically reactive surface, which can host a variety of moieties, is appealing for chemists, biologists and material scientists 9,10 . Quantum magnetometry 2,3 is an example of an emerging technology that will directly benefit from the availability of nanocrystals with welldefined sizes in the 5-nm range, because the sensitivity to single spins is inversely proportional to the cube of the distance between the sensor (that is, the nitrogen-vacancy (NV) centre) and the spin being detected.Producing and detecting NV colour centres in isolated 5-nm detonation nanodiamond has been controversial, and there has been some scepticism regarding their stability as a useful emitter in a discrete crystal. For example, theoretical calculations of the crystal energy budget favour the location of nitrogen on the surface rather than in the core, which seems to explain the limited observation of NV centres in chemical vapour deposition and high-pressure high-temperature grains of less than 40 nm in size 11,12 , and favours the prediction that nanodiamonds smaller than 10 nm in size do not contain NV centres 7,13 . Although sub-10-nm nanodiamonds with NV centres have been produced using a top-down approach (milling luminescent high-pressure hightemperature microdiamonds into 7-nm particles 6,14 ), the question of NV stability in isolated detonation nanodiamonds persists.In aggregated detonation nanodiamonds (agglomerates and agglutinates 8 ), high-sensitivity, time-gated luminescence and electronic paramagnetic resonance spectroscopy have been used to extract a weak NV signal from a strong luminescence background 5 . The experiments highlight the eclipsing nature of the graphitic surface layers in nanodiamond aggregates-NV centres were simply not visible through the broadband luminescence from the surface and grain boundary material. To distinguish the NV spectral signature from the large grain boundary luminescence overhead, diamond synthesis yielding discrete sub-10-nm detonation nanodiamonds is vital. Here, we use a robust deaggregation and dispersion method, which diminishes the crystal-crystal interaction to...
