Fundamental information on the behavior of excited chlorophyll molecules packed within the confinements of nanosized photosystems I and II, following absorption of light, is presented. Using a 100 femtosecond laser with nanojoule (nJ) pulse energy and a one picosecond streak camera, we observed the light emitted from the nanostructured photosystems without oscillations or hops. The fluorescent exponential decay profiles and high efficiency within the nanostructure suggest that light coherently drains out as a unit. This implies that "quantumness" is linked to quantum confinement on the nano scale.

量子纳米结构光系统限制内的超快时间尺度上的光合作用

介绍了在吸收光后，包裹在纳米级光系统 I 和 II 范围内的激发叶绿素分子行为的基本信息。使用具有纳焦 (nJ) 脉冲能量的 100 飞秒激光器和 1 皮秒条纹相机，我们观察到从纳米结构光系统发出的光没有振荡或跳跃。纳米结构内的荧光指数衰减曲线和高效率表明光作为一个单元相干地排出。这意味着“量子性”与纳米尺度上的量子限制有关。
