近年来，在半导体纳米晶体的荧光衰减过程中观察到了幂律动力学现象，并在Monte Carlo模拟的基础上提出了一个模型并进行了分析，以阐明幂律荧光衰减与幂律闪烁之间的关系。然而，基于蒙特卡罗模拟的模型分析不是决定性的。本文给出了该模型的解析解。利用分析结果严格证明了幂律闪烁指数与幂律荧光衰减指数相同。
Recently power law dynamics was observed in the fluorescence decay from semiconductor nanocrystals and a model was proposed and analyzed on the basis the of Monte Carlo simulation to clarify the relation between the power law fluorescence decay and the power law blinking. However, analysis of the model on the basis of the Monte Carlo simulation is not decisive. In this paper we present the analytical solution of the model. The analytical result is used to prove rigorously that the exponent of the power law blinking and that of the power law fluorescence decay are the same.
