Material characterization. (a) UV-Visible extinction spectra of 2D MoS2 nanosheets dispersion at 620 g and 1000 g. (b) Raman spectra of the two main vibrational modes \({\nu }_{2g}^{1}\) and A1g of MoS2 nanosheets centrifuged at 1000 g and 1400 g. Raman shift in the region from 380–412 cm−1 range represents MoS2 nanoflakes in the range from 2–4 layers.
