| Outline of Final Research Achievements |
By using liquid phase laser ablation technique, we have investigated direct-synthesis of nanodiamond with a diameter of several nanometers, which is difficult to synthesize by detonation method. We have developed high efficient synthesis method of nanoparticle by using femtosecond double-pulse trains. The synthesized nanodiamonds have a conventional cubic diamond structure and high dens phase of hexagonal diamond structure (Lonsdaleite). In the case of graphene oxide dispersed in cyclohexane, the surface of synthesized nanodiamond was covered with a functional group such as OH, C=O, and COOH groups. The photoluminescence of the nanodiamond synthesized in cyclohexane was broadened and red-shifted compared to that in pure water. Furthermore, in the case of the nanodiamond synthesized in aqueous ammonia, amide and ammonia groups were adsorbed on the nanodiamond surface, leading to much higher PL intensity (at least 40 times).
