We experimentally demonstrate the enhancement of fluorescence from quantum dots excited by interaction with surface plasmon polaritons on nanostructured metal surfaces. The relationship between observed enhancement and geometrical factors of the surface structure has been used to explore the behavior of quantum dots on different substrates. Imaging using standard fluorescence optical microscopy clearly demonstrates a strong dependence of fluorescence enhancement on fundamental parameters for periodic surface structures.
我们通过实验证明了在纳米结构金属表面的表面等离激元激发现象作用下，量子点的荧光增强。观察到的增强与表面结构的几何因素之间的关系被用来探索量子点在不同衬底上的行为。使用标准荧光光学显微镜进行成像，清楚地证明了荧光增强与周期性表面结构的基本参数之间存在强烈的依赖关系。
