Atmospheric-pressure microplasma-assisted electrochemistry was used to synthesize Ag nanoparticles (NPs) for plasmonic applications. It is shown that the size and dispersion of the nanoparticles can be controlled by variation of the microplasma-assisted electrochemical process parameters such as electrolyte concentration and temperature. Moreover, Ag NP synthesis is also achieved in the absence of a stabilizer, with additional control over the dispersion and NP formation possible. As the microplasma directly reduces Ag ions in solution, the incorporation of toxic reducing agents into the electrolytic solution is unnecessary, making this an environmentally friendly fabrication technique with strong potential for the design and growth of plasmonic nanostructures for a variety of applications. These experiments therefore link microplasma-assisted electrochemical synthesis parameters with plasmonic characteristics.
大气压微等离子体辅助电化学用于合成用于等离子体应用的银纳米粒子 (NP)。结果表明，通过改变微等离子体辅助电化学过程参数，如电解质浓度和温度，可以控制纳米粒子的尺寸和分散性。此外，还可以在没有稳定剂的情况下实现 Ag NP 的合成，并可以进一步控制分散性和 NP 的形成。由于微等离子体直接还原溶液中的 Ag 离子，因此不需要将有毒还原剂掺入电解液中，这是一种环保的制造技术，对于设计和生长各种应用的等离子体纳米结构具有很强的潜力。因此，这些实验将微等离子体辅助电化学合成参数与等离子体特性联系起来。
