FIG. 1.

(A) and (B) Two laser focusing conditions for synthesis of Ag particles and measurements of their Rayleigh scattering spectra. (C) Solid lines: calculated Rayleigh scattering spectra of spherical Ag particle with diameter from 20 to 100 nm at intervals of 10 nm. Squares and circles: maximum cross section of experimental Rayleigh scattering of Ag particles under the focusing conditions (A) and (B), respectively. Inset of (C): typical images of Rayleigh scattering spots of synthesized Ag particles under the focusing conditions (A) (the left panel) and (B) (the right panel). Scale bars in the panels are . (D) Spectra with a solid and dashed line: the Rayleigh scattering spectrum of an Ag particle synthesized by the focusing condition (B) and that of an Au particle in 80 nm diameter as a reference for the scattering cross section, respectively.12) (E)–(G) Experimental Rayleigh scattering spectra (gray lines) and (solid lines) of five Ag particles synthesized by the focusing condition (A). A set of diameters (, , and ) in nanometers in Eq. (1) is (39, 40, 25), (38, 37, 27), (35, 17, 40), for (E)–(G), respectively. The inset of (E) is a coordination system used for the current calculation.
