在这里，我们证明了用等离子体聚合沉积的 SiO2 介电间隔物制备的准自支撑金纳米棒阵列支持表面增强荧光 (SEF)，同时保持高信号再现性。我们表明，可以在增强的辐射衰减率和非辐射衰减率之间找到平衡，使荧光强度最大化。使用 30 nm 间隔层厚度优化的 SEF 信号显示出 3.5 倍的增强，信号方差为
Here, we demonstrate that quasi self-standing Au nanorod arrays prepared with plasma polymerisation deposited SiO2 dielectric spacers support surface enhanced fluorescence (SEF) while maintaining high signal reproducibility. We show that it is possible to find a balance between enhanced radiative and non-radiative decay rates at which the fluorescent intensity is maximized. The SEF signal optimised with a 30 nm spacer layer thickness showed a 3.5-fold enhancement with a signal variance of
