Abstract
We report on the observation of optically active colour centres
based on Nickel-Nitrogen impurities in natural diamond samples.
These emitters can efficiently generate single photons in the near
infrared. Their photoluminescence is perfectly stable at room
temperature and has several striking features, such as a narrow band
emission around 780 nm and a short photon emission lifetime
around 2 ns. We present a detailed study of their photophysical
properties measured under continuous-wave excitation.
