    • It is noted that the equations presented by Heath et al. suggest that they assumed the particles to be surrounded by air rather than the solvent acetonitrile used in their work (Ref.). However, only minor qualitative changes are introduced (whereas the quantitative absorption is increased by a factor of ∼3) when the dielectric constant of acetonitrile [see also P. Norman, Y. Luo, and H. gren, J. Chem. Phys. 107, 9535 (1997)] is introduced instead of 1 for air. 10.1063/1.475250

    • The atom number density in the nanocrystals may differ from that of the bulk material. However, as the nanocrystals retain the bulk crystal structure and bond lengths within a few percent, the error will be insignificant
