Carbon nanodots (CDs) with size dependent fluorescence are synthesized from multi-walled carbon nanotubes (MWCNTs) under continuous flow in a vortex fluidic device (VFD) when irradiated by a pulsed laser with a wavelength of 1064 nm, without subsequent passivation procedures. The CDs have a relatively narrow size distribution averaging ca. 6 nm in diameter, and have low cytotoxicity and high colloidal stability with the highest emission intensity of the solution at 450 nm under a 345 nm excitation wavelength. Further downstream processing on the as-processed CDs revealed tunability of the emission from 450 nm to 325 nm.

连续流下激光辐照涡流介导的发光碳纳米点的合成†

当在波长为1064 nm的脉冲激光辐照下，由多壁碳纳米管（MWCNT）在涡流流体装置（VFD）中连续流动下，通过多壁碳纳米管（MWCNT）合成碳纳米点（CD），而无需随后的钝化程序。CD的大小分布相对较窄，平均约为。直径为6 nm，具有低的细胞毒性和高的胶体稳定性，在345 nm的激发波长下，在450 nm处溶液的发射强度最高。在加工后的CD上进行的进一步下游处理显示了从450 nm到325 nm的发射可调性。
