硫酸镍与乙酸镍的混合晶体经研磨成 2 μm的颗粒后 ,压制成直径为 10mm的薄片作为靶材 ,以TEACO2 激光辐照 ,得到粒度为 10至 2 0nm的NiSO4/Ni(Ac) 2 纳米粒子 ,其中含少量Ni2 O3 。气体产物为水和乙酸。激光功率密度为 10 8W .cm-2 量级。讨论了激光作用的机理。本文提供了一种用激光烧蚀法制备其化学成分与靶材尽可能相似的纳米粒子的方法
The mixed crystals of nickel sulfate and nickel acetate were ground to 2 μm particles and pressed into flakes having a diameter of 10 mm as targets. TEOSO2 laser was irradiated to obtain NiSO4 / Ni (Ac) 2 nano-particles with a particle size of 10 to 20 nm Particles, which contain a small amount of Ni2 O3. Gas products are water and acetic acid. The laser power density is on the order of 10 8 W · cm -2. The mechanism of laser action is discussed. This article provides a laser ablation method for the preparation of its chemical composition and the target as much as possible the method of nanoparticles
