Figures

Image of FIG. 1.
FIG. 1.

Absorption spectra of films containing NCs of different prepared from bilayer units. The curves marked as 100% and 0% correspond to films containing pure and NCs, respectively. The inset shows (57%) the normalized experimental absorption spectrum measured in the film containing NCs with while is a simulated normalized absorption spectrum calculated by the weighted average of the absorption spectra for the samples containing pure and NCs.

Image of FIG. 2.
FIG. 2.

Absorption spectra of films having NCs of compositions close to which have been prepared from bilayer and trilayer units.

Image of FIG. 3.
FIG. 3.

Plan-view HREM images of films containing pure metal [(a) and (c) ] NCs and bimetallic NCs formed from (b) bilayer units ( of ), (d) -core trilayer unit () and (e) -core trilayer unit (). The insets on the left are HREM images of cross-section specimens of the same samples where the deposition direction is indicated as an arrow in the inset in Fig. 3(a).

Image of FIG. 4.
FIG. 4.

SAD patterns of films containing pure metal [(a) and (b) ] NCs and bimetallic NCs formed from (c) -core trilayer unit () and (d) bilayer units ( of ).

FIG. 5.

(a) Features of the NCs and (b) SPR wavelength as a function of : in-plane average diameter and average volume determined from GISAXS, average density determined from HREM and SPR wavelength. The data correspond to films having NCs of the pure metals or formed by bilayer units, and formed by trilayer units.

Tables
