摘　　要：当金属纳米粒子排列成有序阵列结构时,沿阵列平面内传播的衍射波与单粒子局域等离激元共振耦合,将导致等离激元共振急剧窄化,光谱宽度降至2 nm以下.与共振宽度在80 nm以上的常规单粒子共振相比,这种具有高品质因子的衍射耦合等离激元共振称为等离激元表面晶格共振.近年来,关于表面晶格共振研究已成为纳米光子学领域的研究热点,在发光、激光、光伏、通讯、存储以及传感等领域显示出巨大的应用前景.本文主要综述等离激元表面晶格共振的基本原理和性质,包括共振宽度、共振品质、电场增强,探讨了表面晶格共振的测试方法、影响因素以及纳米光学应用.When plasmonic nanoparticles are arranged in highly ordered array,the diffracted wave propagating across the array plane would couple with the localized plasmon resonance supported single nanoparticle,leading to a sharp narrowing of plasmonic resonances with spectral width down to below 2 nm.This induces a potential enhancement compared to a common single particle resonance width of over 80 nm.The extremely high-quality factors of the diffraction coupled resonances are referred to as plasmonic surface lattice resonances.The related topic has attracted widely interest in nanophotonics and has shown their potential applications in light-emitting device,laser,photovoltaic,communication,storage and sensing,etc.The present review describes the foundamental principles andproperties of plasmonic surface lattice resonances,including the spectral width,resonance quality,electric field enhancement,etc.The measurement methods,influencing factors and applications of surface lattice resonance are also discussed.
