WebApr 9, 2024 · Figure S1 (Supporting Information) shows an absorption spectrum of a SWCNT dispersion with a low content of excess, unbound polymer, and no other nanotube species. Repeated spin-coating of such dispersions was used to create thin films of SWCNTs on alkali-free aluminum borosilicate glass or Si/SiO 2 substrates. WebJul 1, 2007 · Fig. 3(a) presents the absorption spectra in terms of the path length without π-plasmon subtraction. The absorbance decreased linearly with increasing number of slide glasses (path length), following Beer's law. The absorbance was drawn as a function of path length at a resonant energy of 1.2 eV in Fig. 3(b).
