The quantum properties of the fluorescence light emitted by diamond nanocrystals containing a single nitrogen-vacancy (NV) colored center are investigated. We have observed photon antibunching with very low background light. This system is therefore a very good candidate for the production of single photon on demand. In addition, we have measured a larger NV center lifetime in nanocrystals than in the bulk, in good agreement with a simple quantum electrodynamical model.

• Magnetometry with nitrogen-vacancy defects in diamond (2013, background): “The sub-wavelength size of the nanocrystal renders refraction irrelevant so that the NV defect can be simply considered as a point source radiating in air [67].”
• Single defect centres in diamond: A review (2006, background): “This is indeed observed for NV centres in diamond nanocrystals [ 51 ].”
• Single-photon sources (2005, background): “However, there is a dark state, presumably a singlet, responsible for bunching in the correlation function (Kurtsiefer et al 2000, Beveratos et al 2001, Jelezko et al 2002).”
• Nitrogen-vacancy centers in diamond: nanoscale sensors for physics and biology. (2014, background): “The radiative lifetime of the excited state is approximately 13 ns for NV centers in bulk diamond (6, 43) and approximately 25 ns for NV centers in nanodiamonds (6, 44), owing to the different index of refraction.”
• Compact Cavity-Enhanced Single-Photon Generation with Hexagonal Boron Nitride (2019, background): “We also calculated the background correction term[50] and found that it is smaller than the significant digits of our measurement result (< 5×10−5), so we conclude that any deviation from 0 is not due to detector dark counts, but rather other noise sources excited through the laser.”
• Enhanced single-photon emission from a diamond–silver aperture (2011, background): “The spontaneous emission rate and intrinsic radiance of the colour centre can be improved by means of the Purcell effect, which can be achieved by coupling diamond nanocrystal”
