摘　　要：本文提出一种独特的激光熔蚀法即在液体中激光熔蚀固体靶制备纳米晶，并且首次在氨水中激光熔蚀石墨靶制备出氮化碳纳米晶。透射电镜（ＴＥＭ）和高分辨率电镜（ＨＲＥＭ）分析表明制备的氮化碳纳米晶由α－Ｃ３Ｎ４、β－Ｃ３Ｎ４和Ｇｒａｐｈｉｔｅ－Ｃ３Ｎ４晶粒组成。A unique laser ablation method is proposed to prepare nano crystals in which graphite target is ablated by high power pulsed laser in liquid ,and nano crystalline carbon nitrides are prepared in ammonia solution for the first time.Transmission electron microscopy(TEM)and high resolution electron microscopy(HREM)are used to characterize the samples,and the results show that there are α C 3N 4,β C 3N 4 and Graphite C 3N 4 particles in the samples.
