  • Title: Spontaneous emission enhancement of a single molecule by a double-sphere nanoantenna across an interface.
    Author: Lee KG, Eghlidi H, Chen XW, Renn A, Götzinger S, Sandoghdar V.
    Journal: Opt Express; 2012 Oct 08; 20(21):23331-8. PubMed ID: 23188296.
    Abstract:
    We report on two orders of magnitude reduction in the fluorescence lifetime when a single molecule placed in a thin film is surrounded by two gold nanospheres across the film interface. By attaching one of the gold particles to the end of a glass fiber tip, we could control the modification of the molecular fluorescence at will. We find a good agreement between our experimental data and the outcome of numerical calculations.
