WebSep 7, 2024 · Here, we study the complex refractive index of neat CdSe/CdS core/shell QD films by using variable-angle spectroscopic ellipsometry to derive the effective complex … Webbehavior of QD solids is difficult because the complex refractive index of QD solids is a composite quantity that is dependent on size, ligand chain length, and the deposition process of the QDs. To address this problem, we show that the intrinsic refractive index of neat CdSe/CdS QDs can be extracted from solution-state absorption data.
