In this paper, new steps toward a better understanding and utilization of high-pressure high-temperature nanodiamonds (NDs) containing nitrogen-vacancy (NV) centers have been taken. NV–-related long-term luminescence oxygenated particles increased in comparison to plasma hydrogenated NDs' NV– luminescence. The optically detected electron spin resonance process can be also significantly affected by ND termination. For H-terminated the NV0 conversion energy is lower than excitation energy, so that delocalized triplet electrons more easily released from original positions drawn electron-attracting localities material. final result study was application luminescent NDs cells, showing detectability standard confocal microscope subcellular distribution cells TEM.
