Responsive optical nanomaterials that can sense and translate various external stimuli into optical signals, in the forms of observable changes in appearance and variations in spectral line shapes, are among the most active research topics in nanooptics. They are intensively exploited within the regimes of the four classic optical phenomena—diffraction in photonic crystals, absorption of plasmonic nanostructures, as well as color‐switching systems, refraction of assembled birefringent nanostructures, and emission of photoluminescent nanomaterials and molecules. Herein, a comprehensive review of these research activities regarding the fundamental principles and practical strategies is provided. Starting with an overview of their substantial developments during the latest three decades, each subtopic discussion is led with fundamental theories that delineate the correlation between nanostructures and optical properties and the delicate research strategies are elaborated with specific attention focused on working principles and optical performances. The unique advantages and inherent limitations of each responsive optical nanoscale platform are summarized, accompanied by empirical criteria that should be met and perspectives on research opportunities where the developments of next‐generation responsive optical nanomaterials might be directed.

刺激响应光学纳米材料

可以感知到各种外部刺激并将其转换为光信号的响应型光学纳米材料，是外观上可观察到的变化和光谱线形变化的形式，是纳米光学领域最活跃的研究主题之一。它们在四种经典光学现象的范围内得到了广泛利用：光子晶体中的衍射，等离激元纳米结构的吸收以及颜色转换系统，组装的双折射纳米结构的折射以及光致发光纳米材料和分子的发射。在此，对这些研究活动的基本原理和实用策略进行了全面回顾。首先概述他们在最近三十年中的重大发展，每个子主题的讨论都以描述纳米结构与光学性质之间相关性的基础理论为指导，并详细阐述了精细的研究策略，重点关注工作原理和光学性能。总结了每个响应式光学纳米级平台的独特优势和固有局限性，并附有应满足的经验标准以及对下一代响应式光学纳米材料的发展可能具有指导意义的研究机会的看法。
