Abstract

This chapter gives a well-rounded presentation of the continuous synthesis of UNCD via laser shock processing (LSP) of graphite particles suspended in water by a Nd:YAG laser system with high power density (109 W/cm2) and short pulse width at room temperature and normal pressure, which yielded the ultra-nano-crystalline diamond in size of about 5 nm. X-ray diffraction, high-resolution transmission electron microscopy, and laser Raman spectroscopy were used to characterize the nano-crystals. The method studied is helpful in understanding the formation mechanism and enhancing the yield rate of nano-diamond.
