Chirality distribution of SWNTs synthesized using catalyst with and without undergoing pretreatment. (a–c). IPL(6,4)/IPL(6,5) as a function of (a) H2O concentration, (b) H2/N2 ratio, as well as (c) temperature and time of pretreatment. (d,g) PLE maps, (e,h) UV-Vis-NIR spectra, and (f,i) chirality maps of SWNTs growth achieved (d–f) without and (g–i) with catalyst pretreatment. The colors shown in (f) and (i) indicate the concentration of different chiralities decreasing in the order of red, yellow, green, and blue.
