Abstract
Section titled āAbstractāThe manipulation of the charge states of nitrogen-vacancy (NV) centers in diamond is a prerequisite for next-generation quantum sensing, communication, and computing. Here, we use phonon-assisted anti-Stokes excitation to realize the reversible conversion between the NV0 and NV- states. In this case, we observe two decay processes of NV- centers with lifetimes as long as tens of seconds. By studying the kinetics of spectral structure evolution of NV- states, we find that the spectral structure of the NV- center is modulated by the charge state transition process under anti-Stokes excitation. We propose that the main reason is the local electric field generated by the ionization of the NV-, which changes the radiation environment of the color centers. Our results might provide an alternative method to control the charge states of nitrogen-vacancy centers.
