Abstract Metallic surface nanopatterns are prepared by a template‐confined dewetting process with multiple structural controllabilities. The morphology of the building blocks is homogeneous throughout nanopatterns, as proceeds separately in each bowl. features units patterns highly dependent on annealing temperature. Importantly, size and composition nanoparticles can be pre‐calculated designed manipulating thickness evaporated metallic films. heating temperature influence surface‐enhanced Raman scattering (SERS) plasmonic properties, thus tuning localized plasmon resonance peaks over broad range (from visible to near infrared). introduction silver gold enhances SERS performance dramatically. This work not only provides powerful route fabricate but also supplies platform study mechanism complicated processes metals.
