Abstract
Gold nanostructures have very suitable physical properties for plasmonic applications but do not stick on glass substrates. One usually uses a chromium adhesion layer that gives good mechanical adhesion but quench the plasmon. We developed a new adhesion process that permits a covalent bonding between gold and glass thanks to an MPTMS molecular layer throughout nanolithography pro- cess. We demonstrate that this new adhesion layer allows an improvement of the optical properties of the gold nanopar- ticles as well as an essential improvement of their surface- enhanced Raman scattering performances.
