Nanocrystallite preparation by pulsed-laser-induced reaction at liquid-solid interface

摘要

A novel method, pulsed-laser induced reaction at liquid-solid interface (PLIIR), which is used to synthesize nano- crystallite, is developed. Nano-crystalline diamond with hexagonal lattice and cubic lattice and carbon nitride, which phases include $alpha@-C$-3$/N$-4$/, graphite-C$-3$/N$-4$/, $beta@-C$-3$/N$-4$/ and cubic-C$-3$/N$-4$/, are synthesized by this approach. Transmission electron microscopy (TEM), high resolution electron microscopy (HREM) and other methods are used to characterize the structures of the nano-crystallite. Graphite-C$-3$/N$-4$/ and cubic-C$-3$/N$-4$/ are reported for the first time in experiment.
