在飞秒量级下研究了一维半导体聚乙炔的光致吸收随时间的变化。发现诱导吸收出现在小于150飞秒的时间内。的吸收衰减的动力学进行测量和比较的基础上成对重组的一维链上的模型。
The time dependence of photoinduced optical absorption in the prototype one-dimensional semiconductor, polyacetylene, is investigated with femtosecond resolution. It is found that the induced absorption appears in less than 150 fsec. The dynamics of the absorption decay are measured and compared with a model based on geminate recombination on a one-dimensional chain.
