| description | In this study, a composite silver nanostructure is presented to serve as the platform for highly efficient plasmon-enhanced fluorescence (PEF). The composite nanostructure is realized by first employing nanosphere lithography (NPL) combined with reactive ion etching (RIE) technology to create a silver nanopyramid array, which is then further modified with silver nanoparticles. Utilizing DCJTB as the fluorophore, this composite nanostructure is found to outperform the use of either silver nanoparticles or silver nanopyramid array. Notably, it not only enhances the photoluminescence (PL) but also reduces the carrier lifetime. The influence of the particle size of silver nanoparticles and the height of the silver nanopyramids is also investigated. It is found that larger silver nanoparticles and higher silver nanopyramids lead to stronger local surface plasmon resonance (LSPR), thereby enhancing the PEF phenomenon. Compared with the performance of using bare glass substrate, the PL intensity of using the composite nanostructure is enhanced to 19.4 times and the carrier lifetime is shortened by 61%. |
