摘要
The angle resolved surface enhanced Raman scattering (SERS) on two-dimensional Ag hole arrays has been studied as a function of hole size. The Raman enhancement factor has been found to increase with increasing hole size. In particular, by correlating the Raman mappings with the dispersion relations, the enhancement has been attributed to fast surface plasmon polariton radiative decay rate and strong coupling efficiency. Our results indicate that it is possible to optimize the geometry of the arrays to obtain desirable SERS.
