【摘要】 卤化银的感光过程是一个光电子衰减动力学过程,对卤化银感光材料的光作用衰减动力学进行研究,能从根本上探索感光过程的微观机理.实验上采用微波技术只能测得自由光电子的衰减信号,无法区分卤化银中的各种俘获中心对光电子衰减的作用.而这种计算机模拟方法不仅可以得到自由光电子的衰减曲线,还可同时获得各种俘获中心中载流子的行为曲线.因此可弥补实验的不足,实现对卤化银感光过程微观机理的深入研究.本文详细地介绍了光电子衰减动力学的模拟过程.更多还原

【Abstract】 The photographic process is a photoelectron decay kinetic process. studying the photo-action decay kinetics of silver halide is essential to probe into the fundamental microscopic mechanism of photographic process. On experiment, it can only measure the signal of free photoelectron decay by using microwave technique, which can not distinguish the influence of all kinds of trapping centers on the decay of free photoelectrons. However, through computer simulation, it can obtain not only the decay curve of free photoelectrons, but also the behavior curve of carriers in all kinds of trapping centers. That can make up the deficiency of experiment and be advantageous to the study of the microscopic mechanism. In this paper, the simulation process of the photoelectron decay kinetics is introduced in detail.更多还原
