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…
Mn--Cr dopant association in dilute co-doped revealed by combined EPR and optical spectroscopy
Apoko S. Omondi, Mátyás M. Rudolf, Nikoletta Jegenyés +5
Efficient and durable phosphors made from abundant elements underpin energy-saving solid-state lighting, near-infrared light sources for sensing, and X-ray and biomedical imaging.…
Precursor stoichiometry controls dopant structure, defect chemistry, and valence in Mn-doped ZnGaO nanocrystals
Mátyás M. Rudolf, Gábor Bortel, Nikoletta Jegenyés +5
The luminescence of doped nanocrystals is usually optimised through the activator; here we show that the host cation ratio is an equally decisive, and largely overlooked, design va…
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…
