Anisotropic quantum nanostructures have attracted a lot of attention due to their unique properties and a range of potential applications. Magnetic circular dichroism (MCD) spectra of semiconductor CdSe/ZnS Quantum Rods and CdSe/CdS Dot-in-Rods have been studied. Positions of four electronic transitions were determined by data fitting. MCD spectra were analyzed in the and terms, which characterize the splitting and mixing of states. Effective values of and terms were determined for each transition. A relatively high value of the term is noted, which is most likely associated with the anisotropy of quantum rods.
各向异性量子纳米结构因其独特的性质和一系列潜在应用而备受关注。对半导体CdSe/ZnS量子棒和CdSe/CdS棒中量子点的磁圆二色性(MCD)光谱进行了研究。通过数据拟合确定了四个电子跃迁的位置。从表征态的分裂和混合的项对MCD光谱进行了分析。确定了每个跃迁的项和项的有效值。注意到项的值相对较高,这很可能与量子棒的各向异性有关。
