Weak Raman signals can be strongly enhanced using the so called surface enhanced Raman scattering (SERS) effect employing e.g. nano-structured metal surfaces. In order to get a deeper understanding of the enhancement mechanisms, silver nanoparticles of well defined shape and size prepared by nanosphere lithography were applied instead of randomly roughened silver films. The dependence of SERS spectra of copper phthalocyanine (CuPc) on the film thickness is discussed. For this purpose monitoring of the Raman signal during deposition of the organic film was performed in situ.
