ABSTRACT
This work reports a simple and versatile method with innovative application of photoresist film for fabricating ordered hemispherical nanodot arrays with tunable structural parameters as large-area surface enhanced Raman scattering (SERS) substrate with high performance. The substrate is fabricated by evaporating Au on the regularly patterened aluminum template of pits arrays formed from the anodization of Al. A key point in our method is coating a photoresist layer on the fragile Au film to support the film before separating it from the Al template, which insures the integrity of the film on large area. Taking Rhodamine 6G as probing molecules, SERS spectra are investigated. The convenience of preparation as well as the high performance for the SERS signals makes the prepared substrates a promising candidate for SERS sensing or detecting.
