Optical properties of Au nano-particles contained TiO(2) inverse opal

The fabrication of Au(3+) containing 3-dimensional ordered PS-TiO(2) has been accomplished by the liquid Phase Deposition (LPD) method using polystyrene (PS) colloidal crystal as template. The interstitial spaces of template were completely filled with deposited oxide by the LPD. After calcination, template was completely removed simultaneously Au(3+) was reduced to Au, and well-ordered 3D macro porous Au nano-particles dispersed TiO(2) was formed. The obtained AU-TiO(2) inverse opal was characterized by SEM, TEM, XRD, and VIS spectroscopy.
