Abstract
The potentialies of a system of parallel microscratches drowed on a PET film metallized with silver and copper using a Vickers indenter as an active Surface-enhanced Raman spectroscopy (SERS) surface have been investigated. It is shown that the magnification of the SERS signal for rhodomine is proportional to the total length of microscratches in the laser spot and increases after their application due to the relaxation of the polymer backing. The results of the microscratch geometry analysis by an atomic force microscopy and scanning electron microscopy methods indicate the probability of the location of "hot points" along the "dumps" of metal along the shores of scratches, as well as on nanoroughnesses along their inner walls.© 2017 Elsevier Inc.
