Dynamic theory of two-photon correlators in the spectroscopy of single impurity centers

Игорь Сергеевич Осадько

A dynamic theory of two-photon correlators measured in experiments with single molecular impurity centers has been developed. The theory takes into account the interaction between optically active electrons of an impurity center and phonons, excitations in tunneling systems of polymers and glasses, and transverse electromagnetic field. Both the correlator measured in the start-stop regime and the “full” correlator have been analyzed, and equations for these correlators have been derived. An equation relating these two correlators has been also obtained. The effect of the triplet level of an impurity molecule on the correlators leading to bunching of spontaneously emitted photons has been studied. The two-photon correlators have been calculated numerically, and their dependence on the incident light frequency and time between the pairs of detected photons in various realistic situations has been derived.

Measuring the number of (N-V)^− centers in single fluorescent nanodiamonds in the presence of quenching effects

Lun-Hsuan Chen, Tsong‐Shin Lim, Huan‐Cheng Chang

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.
