[Source: Heremans F.J. et al, IEEE, 2016.] A nitrogen vacancy center in a diamond occurs when one carbon atom is missing, and next to this empty lattice site sits a nitrogen atom. Much like an atom in a vacuum binds electrons to it, defect centers, like the nitrogen vacancy center, trap …
Due to the relatively small size of nanodiamond, NV centers can be produced by irradiating nanodiamond of 100 nm or less with medium energy H+ beam. This method reduces the required ion dose and reaction, making it possible to mass produce fluorescent nanodiamonds in ordinary laboratory. … Meer weergeven The nitrogen-vacancy center (N-V center or NV center) is one of numerous point defects in diamond. Its most explored and useful property is its photoluminescence, which allows observers to read out its spin-state. … Meer weergeven Nitrogen-vacancy centers are typically produced from single substitutional nitrogen centers (called C or P1 centers in diamond … Meer weergeven The NV center has a ground-state triplet ( A), an excited-state triplet ( E) and two intermediate-state singlets ( A and E).
