一维非辐射迁移加速能量转移的精确渐近性

Exact asymptotics for non-radiative migration-accelerated energy transfer in one-dimensional systems

G. Oshanin, M. Tachiya

摘要:

我们研究了扩散激发态施主和扩散非激发态受主之间通过多极相互作用或交换相互作用进行的直接能量转移。在激发能的长程转移的情况下,Bray和Blythe [Phys. Rev. Lett. 89,150601(2002)],最初开发的接触扩散控制的反应,我们确定在一维系统中的供体衰减函数的长时间渐近。

英文摘要:

We study direct energy transfer by multipolar or exchange interactions between diffusive excited donor and diffusive unexcited acceptors. Extending over the case of long-range transfer of an excitation energy a non-perturbative approach by Bray and Blythe [Phys. Rev. Lett. 89, 150601 (2002)], originally developed for contact diffusion-controlled reactions, we determine exactly long-time asymptotics of the donor decay function in one-dimensional systems.
