【Abstract】 Cubic boron nitride (c-BN) nanocrystals have been synthesized by high-energy pulsed laser induced liquid-solid interfacial reaction. The liquid and solid materials were analytically pure acetone and h-BN wafers with 96% purity, respectively. It was shown that the diameters of the prepared quasi-spherical c-BN nanocrystals vary from 30nm to 80nm via Transmission electron microscopy (TEM). The X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy were used to characterize the structure of c-BN.更多还原
