Title Study on the process and mechanism of nanomaterials generated by laser ablation in liquids solution
Abstract：Nano-hydroxy stannate have shown advantages in many industries because of their superior properties. The Nano-hydroxy stannate prepared by laser liquid ablation have shown superior performance over other Nano-hydroxy stannate. Laser ablation of nanomaterials has become a hot topic. In order to study the process and mechanism of laser liquid phase ablation process, two metal targets of Zn target and Sn target were used as experimental objects. Two metal targets were laser ablated by Nd: YAG laser with 1064nm wavelength. The process of using the CCD camera to take pictures of the details of the experiment. The effects of various parameters on the process and mechanism of the preparation of Nano-hydroxy stannate by laser liquid phase ablation were studied by setting different parameters. The samples were characterized by experiments. Through this experiment, the process and mechanism of the preparation of oxide nanoparticles by laser liquid phase ablation were obtained, and the influencing factors were summarized.
