Quartet state of the neutral nitrogen-vacancy center in diamond and optimized spin readout under near-infrared two-photon excitation
Nikoletta Jegenyes, Pál Maák, Vladimir Verkhovlyuk +4
Photoionization of the excited nitrogen-vacancy center (NV-) in diamond leaves the neutral defect in a metastable quartet state of unknown energy. Using two-photon optically detect…

Solution-phase fluorination of nanodiamond: near-surface NV activation and spin relaxation
Szabolcs Czene, Olga Krafcsik, Nikoletta Jegenyés +4
Nanodiamonds hosting luminescent point defects, known as fluorescent nanodiamonds (FND), are a leading platform for quantum technology. The nitrogen-vacancy (NV) centre is the most…
