在这份简报中，我们表明，当金颗粒的互连网络沉积在一个干净的平面表面上时，它们强烈地改变了自组装纳米颗粒附近的光子局域态密度（LDOS）。它们代表了最初平坦的光子LDOS的亚波长图案化的独特架构。此外，我们表明，他们的本地光谱签名是非常适合于生成的网站能够增强分子荧光强度。
In this Brief Report, we show that when interconnected networks of gold particles are deposited onto a clean planar surface, they strongly modify the photonic local density of states (LDOS) in the immediate proximity of the self-assembled nanoparticles. They represent unique architectures for the subwavelength patterning of initially flat photonic LDOS. Moreover, we show that their local spectral signatures are well suited for the generation of sites able to enhance molecular fluorescence intensity.
