title: Enhanced Raman scattering of ZnO nanocrystals in the vicinity of gold and silver nanostructured surfaces.
abstract: nonresonant surface enhanced Raman scattering by optical phonons of ZnO nanocrystals on and beneath silver and gold island films is reported. For both configurations comparable SERS efficiency is observed, proving their potential utility. Variations in peak intensities can be attributed to difference in the morphology of island films on and beneath nanocrystals as well as to variation of the interface between semiconductor and metal. The dominant peaks in the SERS spectra are assigned to surface optical phonon modes.
