In the past few years, the nitrogen-vacancy (NV) center in diamond was the subject of extensive and promising research in the fields of quantum computing, quantum key distribution and quantum sensing. Recently, we experimentally investigated the fluorescence lifetime of the excited state of NV ensembles in microdiamond powder for application in all-optical quantum sensors [1]. To gain insights into the spin dynamics of NV ensembles in microdiamond powder, we simulate the fluorescence lifetime with a simple rate equation model.
