Synthesis of diamond nanocrystals by double ions (40Ar+,C2H+6) bombardment
双离子(40Ar+, C2H+6)辐照合成金刚石纳米晶颗粒

We demonstrate experimentally that an irradiation-induced transformation of multiwalled carbon nanotubes to diamond nanocrystals (DNC) can be realized with double ions ( 40Ar ,C_2H _6) bombardment. This approach is expected to form a new route for synthesis of DNC. The idea of multi-ion irradiation may also be valid for other materials and be used for fabricating nanostructures.
