Abstract
Recently, research has been developing on nanoscale objects (a group of atoms) for which the concept of dielectric constant has a conventional meaning and therefore requires refinement and even analysis. In this paper we analyze the change in the intensity of Raman scattering of nanoobjects placed on a flat substrate. Some variants were shown for which the scattering can vary by more than an order of magnitude. In particular, on an ideal metal substrate, the region of antinode of a standing light wave upon reflection does not extend to the near-surface layer in which the nanoobject is located. And for this reason the Raman scattering decreases by more than an order of magnitude. Conditions are shown under which a decrease in Raman scattering from nanoobjects can be compensated and even increased.
