“…In addition, the photochromic behavior of 575 nm and 638 nm emission bands was observed [12,13] and relation between them was studied [14,15]. In this paper we extend studies of photochromism to a single N-V defect.…”

Photochromism in single nitrogen-vacancy defect in diamond

Photochromism in single nitrogen-vacancy optical centers in diamond is demonstrated.Time-resolved optical spectroscopy shows that intense irradiation at 514 nm switches the nitrogen-vacancy defects to the negative form. This defect state relaxes back to the neutral form under dark conditions. Temporal anticorrelation of photons emitted by the different charge states of the optical center unambiguously indicates that the nitrogen-vacancy defect accounts for both 575 nm and 638 nm emission bands. Possible mechanism of photochromism involving nitrogen donors is discussed.

“…Additionally, the coupling to internal degrees of freedom, e.g., the hyperfine coupling to nuclei, like 13 C and 14 N, was investigated [5]. Although the N-V defect is one of the most studied color centers, it is remarkable that its basic photophysical properties (e.g., the charge state) are not well established yet.…”

Vertical distribution of nitrogen-vacancy centers in diamond formed by ion implantation and annealing

Etching experiments were performed that reveal the vertical distribution of optically active nitrogen-vacancy (NV) centers in diamond created in close proximity to a surface through ion implantation and annealing. The NV distribution depends strongly on the native nitrogen concentration, and spectral measurements of the neutral and negatively-charged NV peaks give evidence for electron depletion effects in lower-nitrogen material. The results are important for potential quantum information and magnetometer devices where NV centers must be created in close proximity to a surface for coupling to optical structures.

“…The charged state of an NV center depends on the NV −/0 transition level relative to the Fermi level. In diamond doped with nitrogen, the Fermi level is 1.7 eV below the conduction band minimum (CBM) [56,57] , and the NV − level is 2.58 eV below the CBM [58,59]. Thus, in free-standing nitrogen-doped diamond, the NV centers deep in the bulk diamond are likely to be in the NV − state (NV 1 in Fig.…”

We propose a multilayer device comprising of a thin-film-based ferromagnetic hetero-structure (FMH) deposited on a diamond layer doped with nitrogen vacancy centers (NVC's). We find that when the NVC's are in close proximity (1-2 nm) with the FMH, the exchange energy is comparable to, and may even surpass the magnetostatic interaction energy. This calls for the need to consider and utilize both effects in magnetometry based on NVC's in diamond. As the distance between the FMH and NVC is decreased to the sub-nanometer scale, the exponential increase in the exchange energy suggests spintronic applications of NVC beyond magnetometry, such as detection of spin-Hall effect or spin currents.
