Solid-state C-13 magic angle spinning NMR spectroscopy characterization of particle size structural variations in synthetic nanodiamonds
Solid-state C-13 magic angle spinning (MAS) NMR spectroscopy has been used to quantify the different carbon species observed in synthetically produced nanodiamonds. Two different diamond-like carbon species were observed using C-13 MAS NMR, which have been attributed to a highly ordered crystalline diamond phase and a disordered crystalline diamond phase. The relative ratio of these different diamond phases was found to vary with the particle size of the nanodiamond materials. (C) 2004 Elsevier B.V. All rights reserved.
