  • Patent number: 10287495
    Abstract: Photoluminescent nanodiamond particles of dynamic synthesis have enhanced photoluminescent properties produced as a result of minimizing the nitrogen content of impurities or imperfections in the nanodiamond lattice and by location of photoluminescent structures on the outer surface of the nanodiamond particles. This inhibits suppression (i.e. inactivity) of emission and enhances the intensity of the emission. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
