我们系统地研究了Ge纳米粒子的制备与脉冲激光烧蚀水中Ge靶材时水层厚度之间的关系。研究发现，所制备的纳米颗粒的平均尺寸随着水的厚度而减小，并且存在一个最佳的水厚度，以获得最大的纳米颗粒产率，这意味着水的厚度可以被视为控制液体中激光烧蚀制备的纳米颗粒的尺寸和产率的重要参数。讨论了相关的物理机制。
We have systematically studied the relationship between the preparation of Ge nanoparticles and the thickness of the water layer upon the pulsed-laser ablation of a Ge target in water. It was found that the average size of the prepared nanoparticles decreases with the thickness of water, and there is an optimum the thickness of water for the largest yield of the produced nanopartciles, which means the thickness of water can be regarded as an important parameter to control the size and yield of the prepared nanoparticles from laser ablation in liquid. The relevant physical mechanism was discussed.
