Real-time ESR tracking for sub-micron 3D magnetic mapping with VB- quantum sensors in hexagonal boron nitride
Jefferson A. O. Galindo, Edwin D. C. Sanchez, Cecília L. A. V. Campos +6
The discovery of spin-dependent luminescent properties of negatively charged boron-vacancy centers () in hexagonal boron nitride (hBN) enabled a new platform for quantum sen…
Absolute Primary Nanothermometry Using Individual Stark Sublevels of Rare-Earth-doped Crystals
Allison R. Pessoa, Thomas Possmayer, Jefferson A. O. Galindo +4
We present two independent optical methods for absolute primary thermometry using rare-earth-doped nanoparticles. Both approaches rely exclusively on the internal energy levels and…
