Metallic nanostructures exhibit strong interactions with electromagnetic radiation, known as the localized surface plasmon resonance. In recent years, there is significant interest and growth in the area of coupled metallic nanostructures. In such assemblies, short‐ and long‐range coupling effects can be tailored and emergent properties, e.g., metamaterial effects, can be realized. The term “plasmonic metasurfaces” is used for this novel class of assemblies deposited on planar surfaces. Herein, the focus is on plasmonic metasurfaces formed from colloidal particles. These are formed by self‐assembly and can meet the demands of low‐cost manufacturing of large‐area, flexible, and ultrathin devices. The advances in high optical quality of the colloidal building blocks and methods for controlling their self‐assembly on surfaces will lead to novel functional devices for dynamic light modulators, pulse sharpening, subwavelength imaging, sensing, and quantum devices. This progress report focuses on predicting optical properties of single colloidal building blocks and their assemblies, wet‐chemical synthesis, and directed self‐assembly of colloidal particles. The report concludes with a discussion of the perspectives toward expanding the colloidal plasmonic metasurfaces concept by integrating them with quantum emitters (gain materials) or mechanically responsive structures.

等离子体等离子表面的胶体自组装概念

金属纳米结构表现出与电磁辐射的强烈相互作用，称为局部表面等离振子共振。近年来，在耦合金属纳米结构的领域中存在重大的兴趣和增长。在这样的组件中，可以定制短程和长程耦合效应，并可以实现紧急特性，例如超材料效应。术语“等离子体超表面”用于沉积在平面上的这类新型组件。在本文中，重点是由胶体颗粒形成的等离质子超表面。它们是通过自组装形成的，可以满足大面积，柔性和超薄设备的低成本制造需求。胶体构建块的高光学质量以及控制其在表面上自组装的方法的进步，将催生出用于动态光调制器，脉冲锐化，亚波长成像，传感和量子器件的新型功能性器件。该进展报告侧重于预测单个胶体结构单元及其组装体的光学性质，湿化学合成以及胶体颗粒的定向自组装。该报告最后讨论了通过将其与量子发射体（增益材料）或机械响应结构集成在一起来扩展胶体等离子体超表面概念的观点。该进展报告侧重于预测单个胶体结构单元及其组装体的光学性质，湿化学合成以及胶体颗粒的定向自组装。该报告最后讨论了通过将其与量子发射体（增益材料）或机械响应结构集成在一起来扩展胶体等离子体超表面概念的观点。该进展报告侧重于预测单个胶体结构单元及其组装体的光学性质，湿化学合成以及胶体颗粒的定向自组装。该报告最后讨论了通过将其与量子发射体（增益材料）或机械响应结构集成在一起来扩展胶体等离子体超表面概念的观点。
