Abstract

Quenching effects, including graphite-shell quenching and impurity quenching, on negatively charged nitrogen-vacancy (N-V) centers in fluorescent nanodiamonds (FNDs) can reduce the fluorescence quantum yield and bring about multiexponential decay fluorescence to FNDs. This causes the number of (N-V) centers to be underestimated when using the photon correlation method, which presumes identical emitters. This study proposes a method that combines time-resolved spectroscopy and photon correlation spectroscopy to modify the number measurement with the photon correlation method. The average number of (N-V) centers in 35 nm FNDs was corrected from 7.6 with the unmodified method to 11.96 with the modified method.
