我们研究了中心纳米孔径周围的圆形波纹的影响，以进一步提高每个发射器的荧光计数率并控制其发射方向性。与裸露的纳米孔径相比，添加单个波纹已经可以显着增加荧光信号。完整的荧光表征可量化随着波纹数量增加而有助于荧光增强过程的激发和发射增益。 (C) 2011 美国光学学会
We investigate the influence of circular corrugations surrounding a central nanoaperture to further enhance the fluorescence count rate per emitter and control its emission directionality. Adding a single corrugation already allows to significantly increase the fluorescence signal as compared to a bare nanoaperture. A complete fluorescence characterization quantifies the excitation and emission gains contributing to the fluorescence enhancement process as the number of corrugations is increased.
