摘要

利用纳秒脉冲激光烧蚀(PLA)在水中金属锌靶上合成纳米结构ZnO/ZnO2。典型的激光脉冲能量为每脉冲40-130毫焦耳。氧化剂的加入使纳米颗粒的产率提高了100%，并大大减小了晶粒尺寸。各种分析技术被应用于产品的表征。据我们所知，这是第一次用激光烧蚀法制备晶粒尺寸为5nm的氧化锌。

Synthesis of nanostructured ZnO and ZnO2 by laser ablation process using third harmonic of Nd:YAG laser

A laser-based method was developed for synthesis of nanostructured ZnO/ZnO2 using nanosecond pulsed laser ablation (PLA) on a metallic zinc target in water. Typical laser pulse energy for PLA process was between 40-130 milli-joules per pulse. The addition of an oxidising agent enhanced the nanoparticle yield by 100% and reduced the grain size drastically. A variety of analysis techniques were applied for the characterisation of products. To the best of our knowledge, this is the first time ZnO2 (zinc peroxide) having grain size of 5 nm are produced using laser ablation.
