Abstract

We systematically studied the characteristics of hybrid perovskite-based surface plasmon nanolasers. If one changes the anion composition of perovskites, the emission wavelength can be easily tuned. We conducted in full-spectrum modeling that featured hybrid perovskite nanowires placed on different SiO₂-coated metallic (Au, Ag, and Al) plates. The proposed nanocavities that supported plasmonic gap modes exhibited distinguished properties of nanolasers, such as low-transparency threshold-gain and low lasing threshold. The corresponding experimental results for the MAPbBr₃ nanolaser on Ag revealed the low-threshold operation. These superior features were attributed to enhanced light-matter interaction with strong coupling. Therefore, the proposed scheme, integrated with hybrid perovskite as gain material, provides an excellent platform for nanoscale plasmon lasing in the visible to near-infrared spectra.

基于钙钛矿的表面等离子纳米激光器的全光谱分析

摘要

我们系统地研究了混合钙钛矿基表面等离子体纳米激光的特征。如果改变钙钛矿的阴离子组成，则可以很容易地调节发射波长。我们进行了全光谱建模，其特征是将杂化钙钛矿纳米线置于不同的SiO ₂涂层金属（Au，Ag和Al）板上。支持等离激元间隙模式的拟议的纳米腔展示出纳米激光的显着特性，例如低透明阈值增益和低激光阈值。MAPbBr ₃的相应实验结果Ag上的纳米激光显示了低阈值操作。这些优越的特性归因于增强的光物质相互作用和强耦合。因此，所提出的方案与杂化钙钛矿作为增益材料集成在一起，为从可见光到近红外光谱的纳米级等离子体激射提供了一个极好的平台。
