    "abstract": "Owing to their unsurpassed photostability, defects in solids may be ideal\ncandidates for single photon sources. Here we report on generation of single\nphotons by optical excitation of a yet unexplored defect in diamond, the\nnickel-nitrogen complex (NE8) centre. The most striking feature of the defect\nis its emission bandwidth of 1.2 nm at room temperature. The emission\nwavelength of the defect is around 800 nm, which is suitable for telecom\nfibres. In addition, in this spectral region little background light from the\ndiamond bulk material is detected. Consequently, a high contrast in\nantibunching measurements is achieved.",
