Impact of charge conversion on NV-center relaxometry [PDF]
Physical review B, 2023 Relaxometry schemes employing nitrogen-vacancy (NV) centers in diamonds are essential in biology and physics to detect a reduction of the color centers' characteristic spin relaxation ($T_1$) time caused by, e.g., paramagnetic molecules in proximity ...

Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond
Accounts of Chemical Research, 2022 Conspectus Relaxometry is a technique which makes use of a specific crystal lattice defect in diamond, the so-called NV center. This defect consists of a nitrogen atom, which replaces a carbon atom in the diamond lattice, and an adjacent vacancy.
