Over the past 20 years, hybrid plasmonics for nanoemitters of light or for nanoabsorbers, based on weak or strong coupling between metallic nanocavities and active media (emissive or absorbing entities), have given rise to important research efforts. One of the main current challenges is the control of the nanoscale spatial distribution and associated symmetry of the active medium in the vicinity of the metallic nanoparticles. In this review, we first recall the main principles of weak and strong coupling by stressing the importance of controlling the spatial distribution of the active medium and present the main approaches developed for achieving this control. Nine different approaches are identified. We then focus our attention on one of them based on plasmonic photopolymerization and discuss the flexibility of this approach in terms of control of the spatial symmetry of the hybrid nanosystem metal–polymer nanoemitters and the resulting polarization dependence of the light emission. The different approaches are analyzed and compared with each other, and some future perspectives and challenges are finally discussed.

在混合纳米等离子体中定位活性培养基的方法。专注于等离激元辅助光聚合

在过去的 20 年里，基于金属纳米腔和活性介质（发射或吸收实体）之间的弱或强耦合，用于光纳米发射器或纳米吸收剂的混合等离子体产生了重要的研究工作。当前的主要挑战之一是控制金属纳米颗粒附近活性介质的纳米级空间分布和相关对称性。在这篇综述中，我们首先回顾了弱耦合和强耦合的主要原理，强调了控制活性介质空间分布的重要性，并介绍了为实现这种控制而开发的主要方法。确定了九种不同的方法。然后，我们将注意力集中在其中一种基于等离激元光聚合的作用上，并讨论了这种方法在控制杂化纳米系统金属-聚合物纳米发射器的空间对称性以及由此产生的光发射的偏振依赖性方面的灵活性。对不同的方法进行了分析和比较，最后讨论了一些未来的前景和挑战。
