“…The parameter ξ is the ratio of excitation efficiency of the NV to NV − . This value is not consistent in the literature and ranges from 0.33 to 1.8 [22,23,35,40]. The value used here lies within this range and is therefore reasonable.…”

“…Interestingly, an increase in the recombination rate has been observed for under NIR illumination for ensembles of NVs in nanodiamonds at 785 nm [23] and for single NV centres in bulk at 766 nm [22]. Both of these wavelengths should not have enough energy to excite the singlet nitrogen; nevertheless, the recombination is still observed.…”

“…Importantly, when the green power is comparable to the typical NV saturation power in our setup (≈ 300 μW), the charge state conversion rate can be faster than 1 × 10 6 s −1 , comparable to the spin polarization rate for NV − , suggesting that fast ionization and recombination processes can occur during the spin initialization and readout times. Since these processes are not spin conserving [32], this fast charge conversion can lead to degradation of the OD-ESR contrast.…”
