摘要
在外光场激励下,金属纳米结构衬底表面所形成的集体电子振荡模式可有效调制其局域电磁场分布,对居于衬底附近的荧光分子的荧光辐射产生调控。其影响因素主要取决于衬底金属表面所形成的电磁振荡模式和电磁场分布性质。归纳了光谱学中表面增强荧光效应研究的关键问题,指出了周期性有序衬底金属增强荧光及其金属纳米颗粒增强荧光研究的主要研究进展。基于局域电磁场增强机理模型,讨论了不同形貌衬底金属对荧光分子的荧光调控机理和影响因素。对表面增强荧光效应的研究前景进行了展望。
Under the excitation of the external light field,the collective electron oscillation mode formed on the surface of the metal nanostructure can effectively modulate the local electromagnetic field distribution,and control the fluorescence radiation of fluorescent molecules near the substrate. The affecting factors mainly depend on electromagnetic oscillation mode and electromagnetic field distribution formed on the surface of the substrate. The key problems in the study on surface enhanced fluorescence effect in spectroscopy are summarized. The main progress of the research of periodically ordered substrate metal enhanced fluorescence and metal nanoparticle enhanced fluorescence is performed. Based on local electromagnetic field enhancement mechanism model,the mechanism and affecting factors of fluorescence regulation of fluorescent molecules on different substrates are discussed. The research prospect of surface enhanced fluorescence effect is prospected.
