【 摘 要 】

This work demonstrates the fabrication of uniform gold nanoarrays by utilizing self-assembled block copolymer (BCP) template, which enables us to finely tune the gold nanostructures by simply adjusting reaction time. We fabricated a series of evolutional gold nanostructures with different reaction time, and investigated their corresponding SERS effects. Results show that the nanostructures have strong size-dependent Raman signal enhancement. This work provides a fast, simple and reproducible way to fabrication of SERS-active substrate with tunable nanostructures.
