纳米等离子体激元学是研究金属纳米结构中表面等离子体激元共振激发介导的轻物质相互作用的新兴研究领域。它允许操纵光的流动及其与纳米级（10（-9）m）物质的相互作用。等离子体共振最有希望的特性之一是它们发生在与物质中典型的电子激发相对应的频率处。这导致局部表面等离子体和放置在金属附近的光发射体（例如分子、染料或量子点）之间出现强相互作用。纳米纤维的最新进展和理论纳米光子学中新概念的发展为旨在减少可用发射体的寿命并提高其衰减速率和量子效率的结构设计开辟了道路。在这篇文章中，一些最相关的实验和理论成果，在过去几年中完成的介绍和分析。
Nanoplasmonics is the emerging research field that studies light matter interactions mediated by resonant excitations of surface plasmons in metallic nanostructures. It allows the manipulation of the flow of light and its interaction with matter at the nanoscale (10(-9) m). One of the most promising characteristics of plasmonic resonances is that they occur at frequencies corresponding to typical electronic excitations in matter. This leads to the appearance of strong interactions between localized surface plasmons and light emitters (such as molecules, dyes, or quantum dots) placed in the vicinity of metals. Recent advances in nanofabrication and the development of novel concepts in theoretical nanophotonics have opened the way to the design of structures aimed to reduce the lifetime and enhance the decay rate and quantum efficiency of available emitters. In this article, some of the most relevant experimental and theoretical achievements accomplished over the last several years are presented and analyzed.
