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
N (natural abundance 0.37%) were applied. Since the reduction of
C affects an increase in T
, N implantation into a CVD diamond with high purity of
C (99.99%) was carried out. As a result, the value of T
for both
NV
and
NV
centers (
NV
centers are created from
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
NV
and
NV
was estimated.

We have measured optically-detected magnetic resonance (ODMR) of single spin of NV center in a high purity C enriched CVD diamond created by
N ion implantation. Detailed ODMR measurements of individual NV centers revealed that both
NV and
NV were created by the
N implantation with a ratio of [
NV]/[
NV]
1 and a high conversion yield of 70-100% for [
NV+
NV]. The spin coherence time of
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.
