如果可以在任何期望的位置合成和集成，则尺寸选择的亚微米球成为非常有用的构建块。特别地，具有与可见光波长相似的尺寸的球体已经吸引了很多关注。在这里，我们展示了在超临界流体中使用脉冲激光烧蚀金盘的尺寸选择的亚微米金球的合成和组装。在研究中获得了四个发现。生成了具有窄尺寸分布的亚微米球，并且多分散性为0.6%。平均粒径控制在600 ~ 1000 nm。找到了一个可规模化合成的热力学条件，实现了微球在金属、碳或塑料基底上的组装。
Size-selected submicron spheres become very useful building blocks if the spheres could be synthesized and integrated at any desired position. In particular, spheres having a similar size to visible-light wavelength have attracted much attention. Here, we show the synthesis and assembly of size-selected submicron gold spheres using pulsed laser ablation of a gold plate in a supercritical fluid. Four findings were obtained in the study. Submicron spheres with a narrow size distribution were generated, and the polydispersity was ≈ 6%. The average diameter was controlled from 600 to 1000 nm. A thermodynamic condition for scalable synthesis was found. The assembly of spheres onto a metal, carbon, or plastic substrate was accomplished.
