Understanding charge transfer (CT) in electron donor-acceptor systems is critical for the development of more efficient organic photovoltaics (OPVs). Donor-acceptor systems are what compose the active layer in OPVs, and when light is absorbed in the activ… Read More

We demonstrate real-time magnetometry by detecting single-photon emissions from a nitrogen vacancy center prepared in the setting of coherent population trapping and by estimating magnetic field from the time series of photon counts, which are correlated… Read More
