本文介绍了利用纳米粒子辅助脉冲激光沉积（NAPLD）技术合成纳米结构ZnO晶体的方法，该方法将烧蚀物质在气相中冷凝形成的纳米粒子传输到衬底上。研究了合成条件对ZnO晶体形貌的影响。在有限的生长条件下，制备了具有六角形和锥体顶面的ZnO纳米棒。ZnO纳米棒生长最关键的工艺参数是气压，其工艺窗口在1.0 ~ 5 Torr之间。
This paper describes the synthesis of nanostructured ZnO crystals by nanoparticle-assisted pulsed-laser deposition (NAPLD), in which nanoparticles formed in the gas phase by the condensation of the ablated species are transported onto the substrate. The influence of the synthesis conditions on the morphologies of the formed ZnO crystals was investigated in detail. ZnO nanorods with a hexagonal- and pyramidal top surface were obtained under limited growth conditions. The most critical process parameter for the growth of ZnO nanorods was gas pressure, whose process window was in the range from 1.0 to 5 Torr.
