由金属和电介质制成的多层衬底上的荧光团的荧光已知可增强100倍以上。在本研究过程中，我们制备了以Ag为金属，Al(2)O(3)为介质的多层衬底，并研究了激发光偏振对多层衬底增强的影响。结果表明，这种增强是由平行于衬底的电场引起的。当使用无偏振光，入射角度为20度时，80 nm厚的Al(2)O(3)可获得最大200倍的增强。
The fluorescence from a fluorophore on a multilayered substrate fabricated by a metal and a dielectric is known to be enhanced by more than 100-fold. In the course of this study, we prepared a multilayered substrate with Ag as the metal and Al(2)O(3) as the dielectric and then investigated the effects of the polarization of the excitation light on the enhancement of the multilayered substrate. It was found that the enhancement was attributed to an electric field oscillating parallel to the substrate. Maximum 200-fold enhancement could be achieved with 80 nm thick Al(2)O(3) when an unpolarized excitation light was used with an incident angle of 20 degrees.
