Morphological and Optical Characterization of High Density Au/PAA Nanoarrays

Figure 3

Reflection spectra of PAA membranes (a) as-prepared after 10 min second anodization and (d) after posttreatment of 70 min pore widening measured at different angles of incident. The variation of peak position (b, e) and peak reflectance % (c, f) as a function of the angle of incident. The effect of 60 min and 70 min pore widening time on (g) reflection spectra of PAA membrane, (h) peak position, and (i) peak reflectance % at 30° angle of incidence.
