Figure 9. The corresponding absorption and ηLDS for (a) 460 nm QD and (b) 640 nm QD samples.
The measured single QD layer absorption (blue) and the calculated LDS efficiency(red) of the same device are shown in the plot. The light blue area marks the photon energy below the absorption edge, where there should be no ηLDS, and our calculation stops at the absorption edge. The dark lines of the ηLDS (at longer wavelengths than the absorption edges) are for visual guiding only.
