用7keV的N-15(I=1/2)离子注入IIa型金刚石，在金刚石中形成了氮空位色心。光学检测磁共振被用来测量单个NV中心的超精细耦合。由注入N-15产生的(NV-)-N-15的超精细光谱可以与由自然N-14(i=1)位产生的(NV-)-N-14中心区分开来。分析表明，每40个注入的N-15原子中就有1个产生光学可见的(NV-)-N-15中心。这份报告最终证明了一种可以测量氮离子注入形成NV中心的产率的机制。
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.
