In this study, we synthesized gold spheroidized particles with sub-micrometer diameters via atmospheric-pressure plasma-assisted processing with inkjet droplets. Microdroplets of chloroauric acid (HAuCl₄) solution were generated by an inkjet device with high reproducibility and exposed to radio frequency plasma. The synthesized sub-micrometer gold particles have a very narrow size distribution (3%–9% standard deviation), and their diameters can be controlled in the 0.3–0.6 μm range by adjusting the concentration of the solution.

使用喷墨液滴的等离子体辅助合成尺寸控制的单分散亚微米金颗粒

在这项研究中，我们通过大气压等离子体辅助处理与喷墨液滴合成了亚微米直径的金球化颗粒。氯金酸 (HAuCl ₄ ) 溶液的微滴由具有高再现性的喷墨设备产生并暴露于射频等离子体。所合成的亚微米的金颗粒具有非常窄的尺寸分布（3％-9％的标准偏差），并且它们的直径可以在0.3〜0.6来控制μ米范围通过调节溶液的浓度。
