Perovskites CsPbX3 (X = Br, Cl, I) nanocrystals(NCs), gain great attention due to their outstanding optical performance. A major limitation of realizing CsPbX3-based lasers by top-down fabrication method is that they can be easily damaged by the solvents used in the lithography/lift-off process and during the dry etching process. Developing a way of the utilization of CsPbX3 NCs in the top-down fabrication method is highly desired. In this part, by simply combining CsPbBr3 NC film with a fine-designed structure, a CsPbBr3 NC thin film-based plasmonic lattice laser is demonstrated by using a pressure-assisted recrystallization process. Due to the low surface scattering loss and good interaction between gain media and Ag NPs, a low threshold single-mode lasing is achieved.

钙钛矿型CsPbX3(X=BrClI)纳米晶(NCS)因其优异的光学性能而备受关注。用自顶向下的方法实现CsPbX3基激光器的一个主要局限性是，在光刻/剥离工艺和干法刻蚀过程中，它们容易受到溶剂的破坏。开发一种在自上而下制造方法中使用CsPbX3 NCS的方法是非常必要的。在这一部分中，通过简单地将CsPbBr3纳米薄膜与精心设计的结构相结合，利用压力辅助再结晶工艺，展示了一种基于CsPbBr3薄膜的等离子体晶格激光器。由于低表面散射损耗和增益介质与纳米银颗粒良好的相互作用，实现了低阈值单模激光。
