研究了纳米壳二聚体对置于二聚体间隙内的单分子荧光的珀塞尔效应。数值结果表明，纳米壳二聚体具有天线的作用，使能量从激发态分子更有效地传递到二聚体，并作为远场荧光辐射的低通滤波器。此外，纳米壳二聚体对荧光的增强因子远高于固体金二聚体。(C) 2009年美国光学学会
The Purcell effect of a nanoshell dimer on the fluorescence of a single molecule placed within the dimer's gap is studied. The numerical results show that the nanoshell dimer acts as an antenna, making the energy transfer from an excited molecule to the dimer more efficient, and as a lowpass filter for the radiation of fluorescence to the far field. Moreover, the enhancement factor of a nanoshell dimer on the fluorescence is much higher than that of a solid Au dimer in the longer-wavelength regime.(C) 2009 Optical Society of America
