论文摘要
我们首次在Brillouin区域的R点[重孔（HH），Light-Hole（LH）和两个旋转轨道带]的R点的Cd Se纳米片的最低四个带结构进行了实验研究，并且由于CDS壳厚度的变化而导致其修饰。在固定激光激发的情况下，介绍了胶体CDSE/CDS纳米平板中激子动力学的实验和理论研究结果。激发是通过强大的纳秒激光进行的，并且使用了泵和探测技术。差分传输光谱特征
We experimentally investigated for the first time the lowest four band structure of Cd Se nanoplatelets at the r point of Brillouin zone [heavy-hole (hh), light-hole (lh) and two spin-orbital bands] and its modification due to the changing of the CdS shell thickness. The results of an experimental and theoretical study of exciton dynamics in colloidal CdSe/CdS nanoplateles are presented in the case of stationary laser excitation. The excitation was performed by means of the powerful nanosecond laser and the pump and probe technique was utilized. The differential transmission spectra peculiarities
