FIG. 1.

NC donor-acceptor ratio dependent quantum efficiency enhancement of the donor-acceptor hybrid solid films consisting of cyan- and green-emitting CdSe/ZnS core/shell NCs.

FIG. 2.

Time-resolved PL kinetics of the only acceptor NC solids and the donor-acceptor hybrid NC solids with 1:1 ratio at the acceptor emission wavelength of 550 nm. Time-resolved PL kinetics of the only donor NC solids and the donor-acceptor hybrid NC solids with 1:1 ratio at the donor emission wavelength of 500 nm are given in the inset.
