摘要

本文将三种金属纳米颗粒（球形银纳米颗粒、三角形银纳米薄片和三角形金纳米薄片）分别置于Eu（TTFA）3掺杂的Su8薄膜上研究了它们对铕配合物薄膜发光的影响. 结果显示，金属纳米颗粒的局域等离子体共振（LSPR）谱对薄膜发光有很好的调控作用. 对于LSPR谱分别与铕配合物激发谱和辐射谱重叠较好的球形和三角形两种银颗粒，相比于未放置颗粒时薄膜的发光，放置有颗粒的发光有明显的增强，其中球形银颗粒的样品的发光增强效果更为明显. 而对于LSPR谱与铕配合物激发谱和辐射谱都不重叠的三角形片状金颗粒，该颗粒对样品的发光则起到了猝灭作用.

Abstract

Spherical silver (Ag) nanoparticles, triangular Ag nanoprisms, and triangular gold (Au) nanoparticles were separately deposited on the Eu(TTFA)3-doped Su8 films. Compared with the fluorescence of films without nanoparticles, the fluorescence of the doped films was greatly enhanced by the two kinds of the Ag nanoparticles, the enhancement is greater for the spherical Ag nanoparticles than that for the triangular Ag nanoprisms. The fluorescence was quenched for the film with Au nanoparticles. Results show that the nanoparticles can both enhance and quench the fluorescence of the films, which depend mainly on the local surface plasmon resonance (LSPR) of the nanoparticles. When the LSPR of nanoparticles overlaps with the excitation or the emission spectrum of the films, the fluorescence would be enhanced. Otherwise the fluorescence of the films would be quenched.
