静态模型中激活剂(受主)发光的衰减

本文通过敏化剂(施主)和激活剂(受主)间能量传递速率的分布函数,得到了CA<1时静态模型中激活剂发光衰减曲线的表示式:Xe-βt+e-γt d/dt f(t)激活剂发光衰减具有的形式。

THE DECAY OF ACCEPTER FLUORESCENCE IN STATIC MODEL

Compared to a large number of works on time evolution of the donor fluorescence1-7], little has been done on that of accepter trap] fluorescence in energy transfer study Recently, Huber presented theoretical expressions of time development of accepter fluorescence for static and fast D-D transfer models under the condition CA <<18]. In this paper, we have arrived at similar conclusion via an alternative method The distribution function of D-A transfer rates is used.The result derived in this way for static model is an extension of the Huber’s. The decay of donor can be expressed as6]F(t)=exp(-λt)f(t),where γ is transition rate of donor in the system without accepter, f(t) is related only with D-D and D-A transfer For static and fast D-D transfer, the distribution function of D-A transfer rates, φ, is independent of time.
