In this project, we wish to realize a novel concept for organic nanoparticle lasers. The goal is to understand the lasing behavior of composite organic-nanoparticle cavities combining plasmonic surface lattice resonances with distributed Bragg reflectors. In preliminary work, we have shown that embedding metal nanoparticles and organic emitters into microcavities allows to realize laser structures. Here, we wish to systematically study these novel structures. We wish to prepare novel highly defined noble metal nanoparticles with varied size and shape and assemble them into periodic structures which show surface lattice resonances. They will be combined with suitable organic materials and embedded in high-Q distributed Bragg reflector-based cavities to achieve excellent lasing properties and in particular highly photostable emission systems. In analogy to a photonic laser/distributed feedback laser (DFB), we plan to study the coherent energy transfer between surface lattice resonance (open cavity design/optical feedback by Bragg scattering) and gain material. Furthermore, we plan to explore mechanically tunable surface lattice resonances.

在这个项目中，我们希望实现有机纳米粒子激光器的新概念。我们的目标是了解激光行为的复合有机纳米粒子空腔相结合的等离子体表面晶格共振与分布式布拉格反射器。在初步工作中，我们已经表明，嵌入金属纳米粒子和有机发光体到微腔允许实现激光结构。在这里，我们希望系统地研究这些新的结构。我们希望制备具有不同尺寸和形状的新型高度限定的贵金属纳米颗粒，并将其组装成具有表面晶格共振的周期性结构。它们将与合适的有机材料相结合，并嵌入高Q分布布拉格反射器为基础的腔，以实现优异的激光特性，特别是高光稳定的发射系统。与光子激光器/分布反馈激光器（DFB）类似，我们计划研究表面晶格共振（开腔设计/通过布拉格散射的光学反馈）和增益材料之间的相干能量转移。此外，我们计划探索机械可调的表面晶格共振。
