The spatial scale at which the effect of surface-enhanced Raman scattering by planar Ag nanostructures manifests itself is investigated experimentally by direct measurements of the dependence of the enhancement factor on the distance between the surface of the Ag nanostructure and a layer of test organic molecules. It is found that the enhancement factor remains almost constant up to distances as large as 30 nm and drops abruptly at larger distances. The obtained dependence is universal for all kinds of organic molecules investigated. The fact that the surface enhancement of Raman scattering manifests itself on such a long spatial scale sharply contradicts the broadly accepted model assuming that the surface-enhanced Raman scattering decreases rapidly at distances as short as 2-3 nm.
