光通过金属层的有效传输已经成为包括发光二极管和太阳能电池在内的各种应用的关键问题。我们在这里报告了一种新的策略，将局部和扩展的表面等离子体结合在一起，以最大限度地提高荧光通过金属薄膜的传输。我们展示了一种由金属纳米颗粒阵列与平面金属层耦合形成的人造材料的分散，可以通过工程设计使金属薄膜在特定方向上100%透射。
Efficient transmission of light through a metal layer has become a key issue for a variety of applications including light-emitting diodes and solar cells. We report here on a novel strategy where localized and extended surface plasmons are combined to maximize the fluorescence transmission through a metallic film. We show that the dispersion of an artificial material formed by an array of metal nanoparticles coupled to a flat metal layer can be engineered to make the metal film, in a specific direction, 100% transmissive.
