Abstract
We report on a detailed nuclear magnetic resonance (NMR) study of hydroxylated diamond nanoparticles. 13C and 1H NMR reveal signals originated from diamond core, hydroxyl, hydrocarbon groups and moisture on the diamond surface. In order to distinguish between the contributions of moisture and other hydrogen-containing groups to the NMR spectra and spin–lattice relaxation, as-prepared and exhausted down to 10-5 Torr samples have been studied. This approach is shown to be useful for correct analysis of the NMR data. Significant reduction in the 13C spin–lattice relaxation time compared with natural diamond and non-exponential behavior of the 13C magnetization recovery were observed similar to the findings on other detonation nanodiamond samples and attributed to the interaction of nuclear spins with paramagnetic defects.
