Efficient generation of single photons is essential for the development of photonic quantum technologies. We have demonstrated that coupling a nanodiamond nitrogen-vacancy (NV) center to CMOS-compatible nanophotonic structures results in significant reduction of the excited state lifetime, increase in the collected single–photon emission, and modification of radiation pattern. In addition, we studied the effect of increased photonic density of states on spin dependent fluorescence contrast.
