Effect of Pore Thickness and the State of Polarization on the Optical Properties of Hexagonal Nanoarray of Au/Nanoporous Anodic Alumina Membrane

Figure 4

Optical properties of NAAMs (a) anodized for different times and (b) illuminated with various states of polarization, (c) variation of with the thickness of NAAM, and (d) calculated absorbance of NAAM showing linear extrapolations to obtain the band gap versus anodization time (the inset). The inset of (a) shows a schematic drawing of the optical setup.
