| 中文摘要 | In this paper, the S-complex of pyrimidine molecule absorbed on silver clusters was employed as a model molecule to study the enhancement mechanism in surface-enhanced resonance Raman scattering (SERRS). We described the chemical enhancement of SERRS through charge transfer (CT) from Ag-20 to pyrimidine on resonance excitation, and electromagnetic enhancement through intracluster charge redistribution (CR) on the electronic intracluster collective oscillation excitation. It is shown that SERRS process of the pyrimidine molecule absorbed on silver clusters with different incident wavelength are dominated by different enhancement mechanisms. Both experimental and theoretical works have been performed to understand the CT process in SERRS. (C) 2013 Elsevier B.V. All rights reserved. |
