ActiveNanotechnologies—Characterization of single-wall carbon nanotubes using ultraviolet-visible-near infrared (UV-Vis-NIR) absorption spectroscopy
纳米技术 单壁碳纳米管的紫外/可见/近红外吸收光谱表征方法
Application Summary AI generated
This standard specifies a method for characterizing single-wall carbon nanotubes (SWCNTs) by analyzing their optical absorption spectra in the ultraviolet, visible, and near-infrared ranges. It is applied in nanotechnology research and industrial quality control to determine the diameter distribution, metallic versus semiconducting content, and purity of SWCNT samples. The method is particularly useful for manufacturers and laboratories evaluating raw nanotube materials or dispersions for use in electronics, composites, and energy devices.
