We report unprecedentedly bright fluorescence from single nitrogen-vacancy centers in nanodiamonds. The intensity enhancement is achieved by placing nanodiamonds in gaps between a metal film and randomly dispersed metal nanoparticles. The shortening of fluorescence lifetime below 1 ns combined with an efficient outcoupling of plasmons into the far-field lead to a detected fluorescence intensity in the range of 107 counts per second (cps). The photostability of nitrogenvacancy centers allows reaching the saturation regime and estimating the total brightness enhancement resulting from the use of plasmonic nanostructures.
