Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond

open access: yesAccounts of Chemical Research, 2022
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. NV centers allow converting magnetic noise into optical signals, which dramatically increases the sensitivity of the ...

Window into NV center kinetics via repeated annealing and spatial tracking of thousands of individual NV centers

open access: yesPhysical Review Materials, 2020
Knowledge of the nitrogen-vacancy center formation kinetics in diamond is critical to engineering sensors and quantum information devices based on this defect. Here we utilize the longitudinal tracking of single NV centers to elucidate NV defect kinetics during high-temperature annealing from 800-1100 $^\circ$C in high-purity chemical-vapor-deposition ...

NV-centers in nanodiamonds: How good they are [PDF]

open access: yesDiamond and Related Materials, 2018
This paper presents a method for determination of the size distribution for diamond nanocrystals containing luminescent nitrogen-vacancy (NV) centers using the luminescence intensity only. We also revise the basic photo physical properties of NV centers and conclude that the luminescence quantum yield of such centers is significantly smaller than the ...
