We report the realization of a solid-state single-photon source with narrow emission in the near infrared. It is based on the photoluminescence of a single nickel-nitrogen NE8 colour centre in a chemical vapour deposited diamond nanocrystal. Room-temperature stable single-photon emission has been observed in the photoluminescence light under both continuous-wave and pulsed excitation. A repetition excitation rate of 20 MHz applied to the single NE8 emitter yielded a photocount detection rate of 30 kcounts/s.
