FIG. 1.

(a) Absorption and PL spectra of only donor (3.4 nm) and only acceptor (5.1 nm) CdTe QDs in water. (b) PL spectra of only donor, only acceptor, and mixed-size QDs films.

Image of FIG. 2.
FIG. 2.

PL spectra of mixed-size CdTe QDs films (, 3, 6, and 9). The inset shows PL spectra of mixed-size QDs (, 3, and 6) in water.

Image of FIG. 3.
FIG. 3.

TRPL spectra of mixed-size CdTe QDs films with various D/A ratios monitored (a) at the donor peak emission (635 nm) and (b) at the acceptor peak emission (734 nm). The inset in (a) shows PL lifetime (at 635 nm) of donors in the mixed film vs D/A ratios. The dashed line denotes the lifetime of only donor QDs film.

Image of FIG. 4.
FIG. 4.

TRPL image of mixed-size CdTe QDs film . The inset shows the temporal evolution of PL spectra.
