Magnetic field-induced enhancement of the nitrogen-vacancy fluorescence quantum yield

Capelli, Marco; Reineck, Philipp; Lau, Desmond W. M.; Orth, A.; Jeske, Jan; Doherty, Marcus; Ohshima, Takeshi; Greentree, Andrew David; Gibson, Brant C.


The nitrogen-vacancy (NV) centre in diamond is a unique optical defect that is used in many applications today and methods to enhance its fluorescence brightness are highly sought after. We observed experimentally an enhancement of the NV quantum yield by up to 7% in bulk diamond caused by an external magnetic field relative to the field-free case. This observation is rationalised phenomenologically in terms of a magnetic field dependence of the NV excited state triplet-to-singlet transition...[Show more]
