Research研究方向

Our group studies light–matter interactions at nanoscale interfaces, where optical fields, electronic states, phonons and molecular excitations become strongly coupled under extreme spatial confinement. These interactions create new photophysical and photochemical mechanisms that cannot be accessed in conventional optical systems.

Built on this central theme, our research develops along three mutually reinforcing directions.课题组研究纳米尺度界面中的光-物质相互作用。在极端空间限域下，光场、电子态、声子和分子激发会发生强耦合，形成传统光学体系难以实现的新型光物理与光化学机制。

围绕这一核心主题，我们的研究沿着三个相互支撑的方向展开。

Light-matter interaction in a nanocavity research overview

Nanoscale Photonics纳米光子学

We investigate plasmonic nanophotonics and optical nanocavities to understand how photons are generated, confined, coupled, manipulated and converted at the nanoscale. By engineering nanostructures and local electromagnetic fields, we seek to control light–matter interactions in regimes relevant to molecular spectroscopy, quantum emission and nanoscale optical energy flow.我们研究等离激元纳米光子学和光学纳米腔，理解光子在纳米尺度上的产生、限域、耦合、调控与转换。通过设计纳米结构和局域电磁场，我们希望在分子光谱、量子发光和纳米尺度光学能量流等相关体系中控制光-物质相互作用。

Mechanistic understanding of nanoscale photonics allows us to develop new spectroscopic instruments and methodologies for probing complex interfaces. We build high-sensitivity, high-resolution, in situ and time-resolved spectroscopy platforms, with increasing emphasis on AI-assisted experiment planning, automated optical control, spectral analysis and closed-loop experimental optimization.对纳米光子学机制的理解使我们能够发展用于探测复杂界面的新型光谱仪器和方法。我们构建高灵敏、高分辨、原位和时间分辨的光谱平台，并逐步加强 AI 辅助实验设计、自动化光学控制、光谱分析和闭环实验优化。

Interfacial Mechanisms界面机制

Using these advanced optical tools, we aim to reveal the physicochemical mechanisms governing functional interfaces. Our interests include charge transfer, energy transfer, molecular adsorption, interfacial polarization, electron spillover, catalytic reaction pathways and dynamic molecular rearrangements at solid–liquid, material–molecule and hybrid nanoscale interfaces.借助这些先进光学工具，我们致力于揭示功能界面的物理化学机制。研究兴趣包括电荷转移、能量转移、分子吸附、界面极化、电子溢出、催化反应路径，以及固-液、材料-分子和杂化纳米界面中的动态分子重排。
