Abstract

Magnetic circular dichroism (MCD) spectra were measured for colloidal CdSe/CdS core–wing nanoplatelets (NPLs). MCD spectra of CdSe cores demonstrate well resolved features which could be attributed to excitonic transitions from heavy hole, light hole and split-off sublevels. A₁/D₀, B₀/D₀ MCD characteristic terms were determined. The values of A₁/D₀, B₀/D₀ terms have no dependence on NPL thickness and are very close to the corresponding values in organic molecules.
