摘　　要：表面增强荧光是一种跨空间的相互作用,受荧光分子和金属纳米颗粒之间距离的影响。核壳结构因其制备方法简便、壳层厚度易调节等特点而成为近几年备受关注的研究课题。本文介绍了几种广泛应用于表面增强荧光研究的核壳结构及其国内外研究进展,主要包括金属纳米颗粒作为核心的壳层结构、金属纳米颗粒作为壳层的壳层结构以及一些其他核壳结构,并结合研究现状对核壳结构的未来发展做出展望。Surface-enhanced fluorescence(SEF)is a cross-space interaction that is affected by the distance between fluorescent molecules and metal nanoparticles.The core-shell structure has become a research topic that has attracted much attention in recent years because of its simple preparation method and easy adjustment of shell thickness.This review introduces several core-shell structures widely used in the study of surface-enhanced fluorescence and their research progress at home and abroad,mainly including the shell structure with metal nanoparticles as the core,the shell structure with metal nanoparticles as the shell,and some other core-shell structures.Then,combined with the research status,the future development of the core-shell structure is prospected.
