Quantum electrodynamics is rapidly finding a set of new applications in thresholdless lasing, photochemistry, and quantum entanglement due to the development of sophisticated patterning techniques to couple nanoscale photonic emitters with photonic and plasmonic cavities. Colloidal and epitaxial semiconductor nanocrystals or quantum dots (QDs) are promising candidates for emitters within these architectures but are dramatically less explored in this role than are molecular emitters. This perspective reviews the basic physics of emitter-cavity coupling in the weak-to-strong coupling regimes, describes common architectures for these systems, and lists possible applications (in particular, photochemistry), with a focus on the advantages and issues associated with using QDs as the emitters.
由于复杂的图案化技术的发展，纳米级光子发射器与光子和等离子体腔耦合，量子电动力学在无阈值激光、光化学和量子纠缠方面迅速找到了一系列新的应用。胶体和外延半导体纳米晶体或量子点（QD）是这些结构中发射器的有前途的候选材料，但与分子发射器相比，它们在这一角色中的应用要少得多。本观点回顾了弱耦合到强耦合区域中发射器-腔耦合的基本物理，描述了这些系统的常见结构，并列出了可能的应用（特别是光化学），重点是使用 QD 作为发射器的优点和问题。
