Nano-crystallite 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 nanostallite, is developed. Nano-crystalline diamond with hexagonal lattice and cubic lattice and carbon nitride, which phasesdudeα-C{sub}3N{sub}4, graphite-C{sub}3N{sub}4, β-C{sub}3N{sub}4 and cubic-C{sub}3N{sub}4, are synthesized by this approach. Trans-mission electron microscopy(TEM), high resolution electron micro-scopy(HREM) and other methods are used to characterize the structures the nano-crystallite. Graphite-C{sub}3N{sub}4 and cubic-C{sub}3N{sub}4 are reported for the first time in experiment.
