Welcome to the Yi Research Group欢迎来到纳米光子学课题组

Nanoscale Light–Matter Interactions at Interfaces We explore how light behaves, transforms and drives matter when confined to nanometer-scale interfaces. At these extreme dimensions, photons couple strongly with electrons, phonons and molecular excitations, giving rise to new photophysical and photochemical mechanisms.纳米尺度界面光-物质相互作用我们探索光在纳米尺度界面中被限域时如何传播、转化并驱动物质变化。在这些极端空间尺度下，光子会与电子、声子和分子激发发生强耦合，从而产生新的光物理与光化学机制。

Our research is organized around three connected directions: plasmonic nanophotonics, mechanism-driven spectroscopic instrumentation, and interfacial physical chemistry. By building optical nanocavities, surface-enhanced spectroscopies and AI-assisted intelligent instruments, we aim to capture weak signals, local fields and transient molecular events, and to reveal complex physicochemical processes at functional interfaces as they happen.课题组研究围绕三个相互关联的方向展开：等离激元纳米光子学、机制驱动的光谱仪器，以及界面物理化学。通过构建光学纳米腔、表面增强光谱和 AI 辅助智能仪器，我们致力于捕捉弱信号、局域光场和瞬态分子事件，并实时揭示功能界面中的复杂物理化学过程。
