单分子荧光过程的Monte-Carlo模拟

MONTE CARLO SIMULATION OF THE LUMINESCENCE PROCESS OF SINGLE MOLECULE

从单分子发光过程中电子在激发态上的停留时间ｔ服从Ｐ（ｔ）＝γｅ－γｔ分布出发，对单分子荧光过程进行Ｍ－Ｃ（Ｍｏｎｔｅ－Ｃａｒｌｏ）随机试验，得到了单分子的激发态相邻两次发光的时间间隔的统计结果以及单分子荧光强度的自相关函数，并对其进行了详细地讨论，这些结果与目前文献报道的实验结果相一致．

Based on the distribution law P(t)=γe -γt for staying time of single molecule in excited state, this paper simulated the luminescence process of single molecule by Monte Carlo method. The distribution of the time interval between two emission events of a single molecule and the autocorrelation function of the fluorescence intensity were obtained. The simulation features the experimental results reported in the literature recently.
