We investigated reusable substrates for Surface Enhanced Raman Spectroscopy (SERS) comprising of nanostructured gratings in quartz coated with silver films. The contribution involves the ED modelling of suited structures, there preparation, and some exemplary SERS results. Although the shown structures were prepared by means of electron lithography they offer the opportunity for easy and economical fabrication using e.g. imprint techniques. We show the influence of technological parameters as well as of thin film properties on the SERS enhancement of the structures. A homogeneous enhancement exceeding 105 is possible across large areas. The SERS enhancement is clearly caused by surface plasmons generated in consequence of the periodic structures and not by surface roughness.
