Abstract

We propose an approach to the analysis and interpretation of spectra of photoinduced circular dichroism (PICD) of semiconductor nanocrystals, in particular, quantum dots, based on comparison of these spectra with the spectra of magnetic circular dichroism (MCD). We show that MCD and PICD spectra have similar features. The values of parameters similar to the well-known parameters A and B of the MCD spectra, which characterize the splitting and mixing of states, are determined from the PICD spectra.

半导体纳米晶体光化学诱导的圆二色性的光谱解释

摘要

我们提出了一种分析和解释半导体纳米晶体，特别是量子点的光致圆二色性（PICD）光谱的方法，基于这些光谱与磁性圆二色性（MCD）光谱的比较。我们证明了MCD和PICD光谱具有相似的特征。由PICD光谱确定类似于MCD光谱的众所周知的参数A和B的参数值，其表征状态的分裂和混合。
