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…
Single-photon emitters and spin-photon interfaces in silicon
Kilian Sandholzer, Ian Berkman, Peter Deák +5
Single photons enable the distribution of quantum information over large distances and thus play a major role in quantum technologies such as communication and computing. Solid-sta…
Thiolation and PEGylation of silicon carbide nanoparticle
Péter Rózsa, Olga Krafcsik, Zsolt Czigány +3
In this study, we implement thiol termination on the surface of few-nanometer-sized silicon carbide (SiC) nanoparticles (NPs) to enable further applications, such as fluorescent bi…
Materials and Spin Characteristics of Nanodiamonds Partially Covered with Amino Groups and Embedded with Nitrogen-Vacancy Color Centers
Nikoletta Jegenyes, Vladimir Verkhovlyuk, Szabolcs Czene +5
Fluorescent nanodiamonds (FNDs) with optically read qubits hold great potential for detecting electric and magnetic fields, temperature, and other nanoscale physicochemical quantit…
