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

胶体 CdSe 纳米片中激子的激子-激子相互作用和级联弛豫

我们首次通过实验研究了布里渊区 r 点处 Cd Se 纳米片的最低四能带结构 [重孔 (hh)、轻孔 (lh) 和两个自旋轨道带] 及其由于CdS 壳厚度的变化。在固定激光激发的情况下，介绍了胶体 CdSe/CdS 纳米片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，并利用了泵浦和探针技术。差分透射光谱特性
