Nitrogen-Vacancy Color Centers in Nanodiamonds as Reference Single-Photon Emitters

Abstract

Quantitative and reproducible optical characterization of single quantum emitters is crucial for quantum photonic materials research, yet controlling for experimental conditions remains challenging due to a lack of an established reference standard. We propose nanodiamonds containing single nitrogen vacancy (NV${}^{-}$) color centers as reliable, stable and robust sources of single-photon emission. We select 4 potential reference emitter candidates from a study of thousands of NV${}^{-}$ centers. Candidates were remeasured at a second laboratory, correlating optical pump power and NV${}^{-}$ center emission intensity at saturation in addition to corresponding $g^{(2)}(0)$ values. A reference nanodiamond is demonstrated to control for experimental conditions, with reproducible and reliable single-photon emission, as a model for a new single-photon emitter reference standard.
