Copper(I) oxide (CuO) nanoparticles (NPs) are selectively prepared in high yields under continuous flow in a vortex fluidic device (VFD), involving irradiation of a copper rod using a pulsed laser operating at 1064 nm and 600 mJ. The plasma plume generated inside a glass tube (20 mm O.D.), which is rapidly rotating (7.5 k rpm), reacts with the enclosed air in the microfluidic platform, with then high mass transfer of material into the dynamic thin film of water passing up the tube. The average size of the generated CuONPs is 14 nm, and they are converted to copper(II) oxide (CuO) nanoparticles with an average diameter of 11 nm by heating the as-prepared solution of CuONPs in air at 50 °C for 10 h.
在涡旋流体装置（VFD）中连续流动的条件下，以高收率选择性地制备了氧化亚铜（Cu₂O）纳米颗粒（NPs），这涉及使用波长为1064 nm、能量为600 mJ的脉冲激光照射铜棒。在一根外径为20 mm且快速旋转（7500转/分钟）的玻璃管内产生的等离子体羽流，与微流体平台内封闭的空气发生反应，随后物质大量转移到沿管向上流动的动态水薄膜中。所生成的Cu₂O纳米颗粒的平均尺寸为14 nm，通过将所制备的Cu₂O纳米颗粒溶液在空气中于50°C加热10小时，它们被转化为平均直径为11 nm的氧化铜（CuO）纳米颗粒。
