    "abstract": "We report on the observation of single colour centers in natural diamond\nsamples emitting in the near infrared region when optically excited.\nPhotoluminescence of these single emitters have several striking features, such\nas a narrow-band fully polarized emission (FWHM 2 nm) around 780 nm, a short\nexcited-state lifetime of about 2 ns, and perfect photostability at room\ntemperature under our excitation conditions. We present a detailed study of\ntheir photophysical properties. Development of a triggered single-photon source\nrelying on this single colour centre is discussed in the prospect of its\napplication to quantum key distribution.",
