Image of FIG. 1.
FIG. 1.

(a) and (b) are low and high magnification TEM images of a ZnSnO nanowire coated with PbS QDs via PLD deposition. (c) EDS spectrum of ZnSnO nanowires coated with PbS QDs. (d) High-resolution TEM image of PbS QDs. The (111) crystal planes of the PbS QDs are indicated. (e) and (f) are the TEM image and corresponding size distribution of PbS QDs on a carbon grid.

FIG. 2.

FTIR data of the ligands in solution and after coating on PbS QDs. (a) and (b) oleic acid; (c) and (d) oleylamine; (e) and (f) MPA. The inset in (f) is the magnified plot in the wavenumber range of 2600-3400 cm.

Image of FIG. 3.
FIG. 3.

(a) IPCE measurement results of PbS QD-coated ZnSnO nanowire photoanodes with and without ligand modification. (b) Same IPCE data in the wavelength range of 800-1400 nm. (c) characteristics of the QDSSCs with and without ligand treatment. A typical in dark is also shown.
