Negatively charged nitrogen-vacancy (NV$$^{-}$$) centers were created in high quality IIa diamonds by nitrogen (N) implantation. To identify implanted N atoms and their incident position, micro ion beams of $$^{15}$$N (natural abundance 0.37%) were applied. Since the reduction of $$^{13}$$C affects an increase in T$$_{2}$$, N implantation into a CVD diamond with high purity of $$^{12}$$C (99.99%) was carried out. As a result, the value of T$$_{2}$$ for both $$^{15}$$NV$$^{-}$$ and $$^{14}$$NV$$^{-}$$ centers ($$^{14}$$NV$$^{-}$$ centers are created from $$^{14}$$N atoms originally existing in the diamond and vacancy introduced by implantation after annealing) was obtained to be about 2 ms. By optically detected magnetic resonance (ODMR) measurements, the creation yield of both $$^{15}$$NV$$^{-}$$ and $$^{14}$$NV$$^{-}$$ was estimated.

We have measured optically-detected magnetic resonance (ODMR) of single spin of NV center in a high purity $$^{12}$$C enriched CVD diamond created by $$^{15}$$N ion implantation. Detailed ODMR measurements of individual NV centers revealed that both $$^{14}$$NV and $$^{15}$$NV were created by the $$^{15}$$N implantation with a ratio of [$$^{14}$$NV]/[$$^{15}$$NV] $$sim$$ 1 and a high conversion yield of 70-100% for [$$^{14}$$NV+$$^{15}$$NV]. The spin coherence time of $$T_2$$ was measured to be 2 ms at room temperature, which is the longest ever recorded in implanted samples. This result is expected to have a significant impact on realizing NV based applications.
