| 摘 要： | 基于聚丁二炔（Ｐｏｌｙｄｉａｃｅｔｙｌｅｎｅｓ）（简写为ＰＤＡ＇ｓ）中光致变色伴随Ｒａｍａｎ谱的显著改变这一事实，认为其先致变色是光诱导相结构转变的结果．建立了描述光诱导相结构转变的数学模型；对于光致变色的微观机理进行了深入的探讨；数值计算了光诱导相结构转变系数对入射光子能量的依赖关系，与实验符合。

| Abstract: | Based on the fact that obvious change of Raman spectra is accompanied by photochromism,this suggests that photochromism is the result of photo-induced structural change.The model for describing photo-induced structural change is presented.The mechanism of photochromism is discussed.The coefficient of photo-induced structural change as the function of incident photon energy is calculated numerically,and it agrees with experimental data. |
