Solvothermal Preparation of Crystal Seeds and Anisotropy-Controlled Growth of Silver Nanoplates

We synthesized silver nanoplates using the solvothermal method and, for the first time, placed them as crystal seeds in a water-based growth solution, thereby successfully achieving the large-scale production of silver nanoplates. The synthesis method enabled independent control of the lateral size and vertical size of the silver nanoplates. More specifically, the lateral size could be adjusted within the range of 565 nm-1.682 μm, while the vertical size was achieved by introducing Cl^- as a capping agent and the vertical size was thickened from 18.28 to 40.41 nm.
