摘要：

Dispersed nanodiamonds just several nanometers in diameter have been successfully synthesized using carbon black as the carbon source by a long-pulse-width laser irradiation in water at room temperature and normal pressure. The produced nanodiamonds can emit strong visible light after simple surface passivation. The light emission is attributed to the surface states related to linkage groups formed on nanodiamond surface. The surface-passivated nanodiamonds with stable photoluminescence have high potential application in bioimaging and medicine. (C) 2008 Elsevier B.V. All rights reserved.
