Résumé

We show that nitrogen is the main impurity contained in detonation nano-diamonds (DNDs), at a concentration of ~16000 ppm. The content of nitrogen-vacancy (NV-) centers in these DNDs is ~2.7 ppm, which is the largest of all known types of nano-diamonds of size <10 nm with artificially created NVcenters. The removal of graphite-like fragments from the DND surface allowed us to detect the characteristic photoluminescence (PL) of the NVcolor centers in individual DND aggregates of sizes from 50-100 to 500-700 nm. We have further confirmed the detection of the negatively charged NVthrough the observation of a strong decrease in the PL intensity when an external magnetic field is applied. Such an effect results from the optically detectable magnetic resonance of the electronic spin triplet ground state of NV-, that cannot be observed in other emitting defects, in a similar spectral range, including the neutral NV 0 centers.
