Super-paramagnetic particles chemically bound to ...
Diamond crystals with a mean size of about 40 nm prepared from synthetic sub-micron . diamond powder by irradiation with 40-keV α-particles followed by annealing at about 1070 . K to increase concentration of NV-centers and milled down to the size of nano-particles. The estimated concentration of NV centers in the diamond nanocrystals was ...
