摘要：
我们解决了在不透明铝膜中研磨的单个纳米孔径内的水-甘油混合物中扩散的罗丹明6 G分子的光动力学速率增强。结合荧光相关光谱和寿命测量，我们报告的相对影响的激发，辐射和非辐射衰减的荧光过程中，给出了一个详细的描述背后的物理整体15倍增强的平均荧光率每个分子。该过程广泛适用于各种各样的纳米结构。
英文摘要：
We resolve the photokinetic rates enhancement of Rhodamine 6G molecules diffusing in a water-glycerol mixture within a single nanometric aperture milled in an opaque aluminium film. Combining fluorescence correlation spectroscopy and lifetime measurements, we report the relative influence of excitation, radiative and non-radiative decay in the fluorescence process, giving a detailed description of the physics behind the overall 15 fold enhancement of the average fluorescence rate per molecule. This procedure is broadly adaptable to a wide range of nanostructures.
