The fluorescence enhancement effect of Rh6G molecules deposited on the silver film substrate decorated with nanohole arrays was investigated in this paper. The prepared substrate, decorated with nanohole arrays, was fabricated with the deposition of silver films onto the anodic aluminum oxide templates through magnetron sputtering method. Compared with the conventional continuous silver film substrate, the prepared substrate shows better enhanced effect. Particularly, the fluorescence enhancement factor has a relationship with the size and period of the nanohole arrays. The experimental observations were analyzed with local surface plasmon resonance model. The results of current work highlight the importance of strong electromagnetic coupling effect in surface enhanced fluorescence.
本文研究了沉积在装饰有纳米孔阵列的银膜基底上的Rh6G分子的荧光增强效应。通过磁控溅射法将银膜沉积到阳极氧化铝模板上制备了装饰有纳米孔阵列的基底。与传统的连续银膜基底相比,制备的基底显示出更好的增强效果。特别地,荧光增强因子与纳米孔阵列的尺寸和周期有关。用局域表面等离子体共振模型对实验观察结果进行了分析。当前工作的结果突出了表面增强荧光中强电磁耦合效应的重要性。
