(a) Spectra of L1 (black) and M1 (turquoise) in toluene and few-layer N1 (magenta) on a quartz substrate. (b) Spectral change on stepwise depositions of single-layer N1 on a quartz substrate. (c) Linear relationship between the absorbance at 500 nm and the number of deposition processes. The magenta dots are extracted from Fig. 6b, and the black solid line corresponds to the least-squares linear fit of the plots.
