Implantation of labelled single nitrogen vacancy centers in diamond using 15N -: art. no. 023113

Nitrogen-vacancy (NV-) color centers in diamond were created by implantation of 7 keV N-15(I=1/2) ions into type IIa diamond. Optically detected magnetic resonance was employed to measure the hyperfine coupling of single NV- centers. The hyperfine spectrum from (NV-)-N-15 arising from implanted N-15 can be distinguished from (NV-)-N-14 centers created by native N-14(I=1) sites. Analysis indicates 1 in 40 implanted N-15 atoms give rise to an optically observable (NV-)-N-15 center. This report ultimately demonstrates a mechanism by which the yield of NV- center formation by nitrogen implantation can be measured.
