(a) Absorption spectra converted from the measured transmission spectra of the multilayered nanosheets on a quartz substrate. Transmission photographs of the samples taken on white paper are also shown. Absorption spectra converted from the measured reflection spectra of the multilayered nanosheets on gold (b) and silver (c) substrates. Reflection photographs of the samples are also shown.
