A topographically patterned PDMS stamp was coated with thin
metal film and swelled under organic vapor to induce the tunable cracking of
the brittle film into metallic nanostructures (see SEM images, scale bars
1 μm). UV/Vis spectra, OLED efficiency, and SERS spectra demonstrate the fine
controllability of the metallic nanostructures, the well-ordered and highly
regulable surface plasmons, and the facile fabrication process.
