摘要： Fluorescence quenching effects on graphene or hydrogen-terminated graphene covered sliver nanoparticles are studied and the results are explained with energy transfer models. The fluorescence signal of R6G is suppressed by the graphene flakes via Förster resonance energy transfer and by the silver nanoparticles via surface energy transfer. The relative fluorescence intensities of R6G are reduced to 28% and 69% on the single-atom-thick graphene flake and the hydrogen-terminated graphene covered silver film, respectively. The mechanism of the quenching effect is illustrated by the energy diagram of electron transition. 出版者： AIP Publishing 出版日期： 2013-02-04 出處： Applied Physics Letters, 2013-02, Vol.102 (5) 資源來源： AIP Publishing Journals 識別號： ISSN: 0003-6951 識別號： EISSN: 1077-3118 識別號： DOI: 10.1063/1.4790825
