Abstract

Fluorescent emitters in nanodiamonds are considered to be a valuable resource for emerging fields such as quantum communication, quantum photonics and biological imaging. In this paper we report a wide range of narrow bandwidth spectral emission lines arising from different color centers at room temperature. We associate the zero phonon lines, observed using confocal microscopy, with previously identified nickel-related centers in high pressure high temperature diamond, with a Si/Ni complex and silicon vacancy defects. In particular we show the first observation of a 850 nm emission in diamond with single photon signature, indicating the potential for diamond to harbor infrared single-photon sources. Index Terms-diamond defects, single-photon emission, confocal microscopy.
