摘要：

Onion-like carbons were synthesized by annealing diamond nanoparticles at 1100-1400 degrees C. The diamond nanoparticles begin to graphitize in the range of 1100-1200 degrees C and all the particles transform into onion-like carbons at 1400 degrees C. The transformation temperature changes with the nanoparticle size. The onion-like carbons exhibit similarity to the original nanoparticles in shape. (c) 2005 Acta Materialia Inc.
