Large-scale Ag nanoislands stabilized by a magnetron-sputtered polytetrafluoroethylene film as substrates for highly sensitive and reproducible surface-enhanced Raman scattering (SERS)
Original language description
Fabrication of surface-enhanced Raman scattering (SERS) nanostructures with both high sensitivity and spectral reproducibility, which are key requirements for routine SERS quantitative (sensing) applications, is a great challenge. Here we report on the multilayered design of SERS-active substrates formed by uniform Ag nanoislands stabilized by a magnetron-sputtered polytetrafluoroethylene (msPTFE) film of nanometre thickness. The preparation of large scale (20 cm2) nanostructures with long (Bmonths) time stability was fast (Bminutes), cheap and repeatable. SERS performance of our substrates was subsequently improved by step-by-step optimisation of the fabrication procedure and introduction of the additional silver layer, separating the supporting glassfrom the msPTFE film, which contributed to the total enhancement factor by another order of magnitude. Such substrates provided high SERS sensitivity with a SERS enhancement factor of about 2 orders of magnitude larger than commonly repo
