Abstract
An effective method for the production of surface enhanced Raman scattering (SERS)active substrates is presented. Nanostructured silver thin films are pulsed laser deposited inan argon atmosphere. The films consist of arrays of nanoparticles whose size is controlledby the Ar pressure. The surface morphology of the films can be tuned by the laser pulsenumber. Nanoparticle size is calculated by a phenomenological model taking intoaccount the dynamics of the laser generated silver plasma. The SERS activity of thefilms is investigated by Raman scattering of adsorbed rhodamine 6G at differentconcentrations.
