Optimum photoluminescence excitation and recharging cycle of single nitrogen-vacancy centers in ultrapure diamond

Beha, K; Batalov, A; Manson, Neil; Bratschitsch, R; Leitenstorfer, A


Important features in the spectral and temporal photoluminescence excitation of single nitrogen-vacancy (NV) centers in diamond are reported at conditions relevant for quantum applications. Bidirectional switching occurs between the neutral (NV0) and negatively charged (NV -) states. Luminescence of NV - is most efficiently triggered at a wavelength of 575nm which ensures optimum excitation and recharging of NV0. The dark state of NV - is identified as NV0. A narrow resonance is observed in the...[Show more]
