Surface-enhanced Raman scattering using gold nanoring substrates is studied. The measured enhancement factors of arrays of single nanorings and nanoring dimers are compared with that of an array of nanodisk dimers. The measured average enhancement factor for the single nanorings is 4.2 x 10(6). The experimental enhancement factors are compared with the electromagnetic enhancement factors predicted by simulations.
研究了使用金纳米环基底的表面增强拉曼散射。比较了单个纳米环和纳米环二聚体阵列的测量增强因子与纳米盘二聚体阵列的增强因子。单个纳米环的平均增强因子为 4.2 x 10(6)。将实验增强因子与模拟预测的电磁增强因子进行了比较。
