FIG. 1.

(a) Emission spectra of QD solutions with 10:1 (square), 1:1 (circle), and 0.1:1 (triangle) donor to acceptor ratios. (b) Emission spectra of QD films with the same ratios. Both emission spectra are normalized. The dashed lines represent the emission peaks of the solution samples. (c) Long decay times τD for 10:1 (square), 1:1 (circle), and 0.1:1 (triangle) samples. (d) “Charging” time τC for the same samples. Insets: time-resolved PL data for the 10:1 and 0.1:1 samples at 550 nm (c) and 650 nm (d).

Image of FIG. 2.
FIG. 2.

(a) Emission intensity and (b) emission peak (λPEAK) as functions of photo-excitation time for donors and acceptors in the 10:1 sample. The comparative curves for films with only donors (long dashes) and acceptors (short dashes) are also shown. Equivalent results for (c) emission intensity and (d) λPEAK for the 1:1 sample and the 0.1:1 sample.

Image of FIG. 3.
FIG. 3.

(a) τD and (b) τC for the 1:1 sample mapped out with varying emission wavelength and 120 min of photo-excitation time. (c) τD and (d) τC for the 0.1:1 sample.
