FIG. 1.

(Color online) Extinction spectra of AgNPs deposited on glass substrates by evaporation for 10, 20, 30, 50, 80, 120, and 180 s, respectively.

Image of FIG. 2.
FIG. 2.

(Color online) Extinction spectra of AgNPs fabricated by evaporation for 50 s (solid line), 80 s (dashed–dotted line), and 180 s (dotted line) after annealed in flowing nitrogen at 200 °C for 10 min. The inset shows the extinction spectrum of the 180 s sample annealed at 400 °C for 10 min.

FIG. 3.

(Color online) SEM images of the 50, 80, and 180 s samples before annealing (a), (b), and (c), and after annealing at 200 °C for 10 min (d), (e), and (f). The corresponding particle size histograms of the annealed samples were shown in (h), (i), and (j), respectively. The AFM images of the 50 and 180 s samples before annealing are shown in the inset of (a) and (c), and the AFM image of the annealed 180 s samples is shown in the inset of (f). The chosen area of all the AFM images is about 500×500 nm.

Image of FIG. 4.
FIG. 4.

(Color online) Coupled extinction spectra of the 50 s (solid line) and 180 s AgNPs (dashed line) before (a) and after (b) annealing at 200 °C for 10 min, after loaded with 10 M R6G.
