Förster能量转移的磁光控制

Magneto-optical control of Förster energy transfer

Rémi Vincent, Rémi Carminati

摘要:

我们介绍了一个一般的框架来研究在纳米结构的环境中发射体和吸收体之间的偶极-偶极能量转移。该理论使我们能够在具有各向异性电磁响应的纳米颗粒存在下解决供体和受体之间的Förster共振能量转移(FRET)。在磁光各向异性的特殊情况下,我们计算了广义FRET率,并讨论了数量级。的距离依赖性,FRET效率和灵敏度的过渡偶极取向的取向不同于标准FRET,可以使用静态磁场作为外部参数进行控制。

英文摘要:

We introduce a general framework to study dipole-dipole energy transfer between an emitter and an absorber in a nanostructured environment. The theory allows us to address Förster Resonant Energy Transfer (FRET) between a donor and an acceptor in the presence of a nanoparticle with an anisotropic electromagnetic response. In the particular case of a magneto-optical anisotropy, we compute the generalized FRET rate and discuss the orders of magnitude. The distance dependence, the FRET efficiency and the sensitivity to the orientation of the transition dipoles orientation differ from standard FRET and can be controlled using the static magnetic field as an external parameter.
