By a variation of a nominal thickness of a film, from 4 to 20 nm and annealing temperature, from 250 to 450оС, nanoisland ensembles have been obtained of different size and surface density. Measurement of spectral dependences of optical reflection and transsmission of such nanostructures on frequency of a plasmon maximum have allowed to establish absorption from the average nanoisland size. These layers have been used as SERS-substrates for obtaining enhancement of Raman scattering from organic molecular layers and inorganic clusters of CdS, prepared by means of colloidal synthesis.
