Abstract:
Bi-metallic patterns with array of Pt discs decorated by Au rings were fabricated onto the substrate by a templated-self-assembly procedure in which multi-step self-assembly processes were involved. The original pattern was established by using the breath figure method. The bi-metallic sample with Au rings exhibited rather high sensitivity as well as great reproducibility within the array in surface-enhanced Raman scattering test.
