Debundling and Selective Enrichment of SWNTs for Applications in Dye-Sensitized Solar Cells

Figure 4

Optical absorption spectrum of CoMoCAT SWNTs dispersed in DI water using TDC (red line) and SDBS (blue line) as surfactant. The absorption peaks from different SWNT species are assigned according to [12, 33]. The shift in the peak positions and widths is due to different surfactants, which change the, dielectric environment. The vertical lines are intended to guide the eyes.
