我们演示了等离子体辅助的能量转移荧光团之间的距离高达7 μ m的顶部上的一个薄的银膜。由于表面等离子体激元的强约束和大的传播长度，能量转移的范围比文献报道的值大近2个数量级。驱动能量转移范围的参数进行了彻底的表征，并与理论预期值非常吻合。
We demonstrate plasmon-assisted energy transfer between fluorophores located at distances up to 7 mu m on the top of a thin silver film. Thanks to the strong confinement and large propagation length of surface plasmon polaritons, the range of the energy transfer is almost 2 orders of magnitude larger than the values reported in the literature so far. The parameters driving the energy transfer range are thoroughly characterized and are in very good agreement with theoretically expected values.
