FIG. 1.

FESEM images of (a) ordered alumina through-pore array induced by solution dipping on PS ( in diameter) colloidal monolayer and (b) Au particle array deposited for at based on the template shown in (a). (c) A local magnification of (b). Scale bars are for (a) and (b) and for (c). (d) The corresponding XRD pattern for sample (b).

FIG. 2.

FESEM images of (a) Au particle array before removal of the alumina template and (b) Au particle film on ITO substrate electrodeposited at for without any template. The scale bars are .

FIG. 3.

SERS spectra of R6G on different substrates. (a) Smooth Au film (sample A), (b) rough Au film (sample B) and [(c) and ] Au particle array before and after laser irradiation (sample C). Raman measurement is conducted with excitation wavelength of from an air-cooled argon ion laser. All of the spectra were the results of a single accumulation. Inset: the FESEM image of a single Au particle in the array after laser irradiation ( per pulse) for 800 shots.
