Figure 4: Luminescence spectra from layered QD systems.

From: Heterogeneous stacking of nanodot monolayers by dry pick-and-place transfer and its applications in quantum dot light-emitting diodes

Figure 4

(a) PL spectra of the multistacked QD monolayers and mixed QD layer. (b) Time-resolved PL decay profiles of the multistacked QD monolayers and mixed QD layer probed at 480 nm. (c) EL device with a multistacked QD layer in the sequence of R/G/B and its EL spectrum. Inset shows a photograph of EL emission from the device. Scale bar, 2 mm. (d) EL device with a multistacked QD layer in the sequence of B/G/R and its EL spectrum. Inset shows a photograph of EL emission from the device. Scale bar, 2 mm.
