An approach based on dual laser beam ablation in liquid is presented for the preparation of bimetal hydroxide. The dynamics of a dual laser-induced bubble dimer is studied by the combination of an inviscid Rayleigh-Plesset model, an ultrafast camera, and time-resolved shadowgraphy experiments. It indicates that the dual laser-induced bubble pair will rapidly merge into a dimer and then undergo evolution as a single bubble, which can promote the agglomeration of two kinds of metal particles in this thermodynamic environment. Moreover, the atomic ratio of bimetal hydroxide with high crystallinity can be precisely adjusted by the dual laser energy ratio without any additives.

液体中双激光束烧蚀诱导的气泡二聚体动力学

提出了一种基于液体双激光束烧蚀制备双金属氢氧化物的方法。双激光诱导气泡二聚体的动力学通过无粘性 Rayleigh-Plesset 模型、超快相机和时间分辨阴影成像实验的组合进行研究。这表明双激光诱导气泡对将迅速合并成二聚体，然后作为单个气泡进行演化，这可以促进两种金属粒子在这种热力学环境中的团聚。此外，高结晶度的双金属氢氧化物的原子比可以通过双激光能量比精确调节，无需任何添加剂。
