Measurement of the Distribution of Site Enhancements in Surface-Enhanced Raman Scattering
2008
Overview
On nanotextured noble-metal surfaces, surface-enhanced Raman scattering (SERS) is observed, where Raman scattering is enhanced by a factor, G, that is frequently about one million, but underlying the factor G is a broad distribution of local enhancement factors, η. We have measured this distribution for benzenethiolate molecules on a 330-nanometer silver-coated nanosphere lattice using incident light of wavelength 532 nanometers. A series of laser pulses with increasing electric fields burned away molecules at sites with progressively decreasing electromagnetic enhancement factors. The enhancement distribution P(η)dη was found to be a power law proportional to (η)⁻¹.⁷⁵, with minimum and maximum values of 2.8 x 10⁴ and 4.1 x 10¹⁰, respectively. The hottest sites (η >10⁹) account for just 63 in 1,000,000 of the total but contribute 24% to the overall SERS intensity.
