J. Mendelsberg, Guillermo Garcia, Hongbo Li, Liberato Manna, Delia J. MillironInevitable variations in size and composition within
nanocrystal
ensembles affect their optical absorbance as revealed by effective
medium theory calculations. We critically analyzed the effects of
such inhomogeneity and of the surface ligands on the localized surface
plasmon resonance absorption of In2O3:Sn and
Cu2–xSe nanocrystal dispersions.
Modeling the absorbance line shape readily provides valuable and quantitative
insight into the structural, electrical, and optical properties of
colloidal nanocrystals.
