为了满足发射体和等离子体纳米天线的精确纳米级布置的挑战，合成和组装方法在准确性和再现性方面继续发展。本文回顾了一些正在开发的“软”化学方法，精密集成和组装的许多战略。我们还讨论了调查的珀塞尔效应，发射方向性控制，和近单位收集效率的光子，发射极-发射极耦合，和更高阶的发射过程中，已被最深入地探讨使用单个发射极（或几个发射极）纳米天线对使用传统的光刻方法制造或动态和可控地操纵使用扫描探针方法。重要的是，这些结果沿着理论分析启发和激励了大规模合成和组装的持续进步。我们强调已被用来创建nanoelectrontor纳米金属混合物，特别是那些提供了特定的激子特性的等离子体效应的组装方法。我们还审查直接合成和化学接头的策略，创造离散的，但空间上扩展较少，电子-金属相互作用。
To meet the challenge of precise nanoscale arrangement of emitter and plasmonic nanoantenna, synthesis and assembly methods continue to evolve in accuracy and reproducibility. This article reviews some of the many strategies being developed for “soft” chemical approaches to precision integration and assembly. We also discuss investigations of the Purcell effect, emission directionality control, and near-unity collection efficiency of photons, emitter–emitter coupling, and higher-order emission processes that have been most deeply explored using individual-emitter– (or several-emitter–) nanoantenna pairs fabricated using traditional lithographic methods or dynamically and controllably manipulated using scanning probe methods. Importantly, these results along with theoretical analyses inspire and motivate continued advancements in large-scale synthesis and assembly. We emphasize assembly approaches that have been used to create nanosemiconductor–nanometal hybrids and, in particular, those that have afforded specific plasmonic effects on excitonic properties. We also review direct-synthesis and chemical-linker strategies to creating discrete, though less spatially extended, semiconductor–metal interactions.
