摘要: 一种独特的方法用来制备纳米晶金刚石,即在丙酮溶液中激光烧蚀石墨靶制备纳米晶金刚石。透射电镜(TEM)和高分辨电镜(HREM)分析表明,所制备的纳米晶金刚石为立方金刚石和六方金刚石晶体。Abstract: Nano-crystalline diamond has been prepared by laser ablation method in which graphite target is ablated by high-power pulsed-laser in acetone solution. Transmission electron microscopy (TEM) and high resolution electron microscopy (HREM) indicate that nano-crystalline diamonds have hexagonal lattice and cubic lattice.
