(a) Optical absorbance density of SWCNT dispersion samples in 273 nm dependent on the process energy. Optical microscopy images are presented for 3 process points: 27 Wh (beginning of the process), 109 Wh (middle), and 218 Wh (end of process). The scale bar in the images is 100 µm. (b) Resonance ratio and spectral width of the 273 nm peak dependent on the process energy.
