Shape transformation of Au crystals from a {111}-bounded octahedron to a {730}-bounded tetrahexahedron (THH) and then to a {310}-bounded truncated ditetragonal prism (TDP) was achieved by a one pot synthesis method. The transformation of the crystal morphology is the result of the synergistic effect of Ag⁺ and O₂/Cl⁻. This work not only provides a way to prepare high-index faceted Au micro/nanocrystals, but also provides new insights into the crystal growth habit.

Au微/纳米晶体从八面体逐步演化为截顶的四角棱镜†

通过一锅合成法实现了Au晶体从{111}结合的八面体到{730}结合的四六面体（THH），再到{310}结合的截短的四角棱镜（TDP）的形状转变。结晶形态的转化是Ag的协同效应的结果⁺和O ₂ /氯^-。这项工作不仅提供了一种制备高折射率多面金微/纳米晶体的方法，而且还为晶体生长习惯提供了新的见解。
