Abstract

Abstract:

Applying the Au/PATP/Au nanoparticles sandwich structure as the model system, a semi-quantitative study on the SERS intensity with the size of Au nanoparticles has been performed. It shows that the SERS intensity increases with the size of Au nanoparticles from 15. 7nm to 66.0nm. The above trend agrees with the calculated value by Schatz, while the SERS enhancement factor is 2-3 orders of the calculated value.

Key words: Surface enhanced Raman scattering(SERS), Au nnoprticles, Assembly, Enhancement factor
