我们观察实验的光谱和空间重塑的荧光发射染料掺杂的介电金属核壳谐振器，支持多极电和磁为基础的cavityplasmonresonances。通过比较实验荧光光谱与基于Mie理论的分析计算，我们能够证明，强整形效应的染料分子的耦合到这些窄带cavityplasmonresonance的结果。此外，我们表明，荧光发射的偏振也可以通过选择性地耦合分子的磁或电为基础的cavityplasmon修改。
We observe experimentally the spectral and spatial reshaping of fluorescence emission in dye-doped dielectric-metal core-shell resonators that support multipolar electric and magnetic-based cavityplasmonresonances. By comparing the experimental fluorescence spectra with analytical calculations based on Mie theory, we are able to demonstrate that the strong reshaping effects are the results of the coupling of dye molecules to those narrow-band cavityplasmonresonances. In addition, we show that the polarization of the fluorescence emission can also be modified by selectively coupling the molecules to the magnetic or electric based cavityplasmons.
