Gold/titanium dioxide (Au/TiO) nanohybrid materials have been widely applied in various fields because of their outstanding optical and photocatalytic performance. By state-of-the-art polymer templating, it is possible to make uniform nanostructured TiO layers with potentially large-scale processing methods. We use customized polymer templating to achieve TiO nanostructures with different morphologies. Au/TiO hybrid thin films are fabricated by sputter deposition. An in-depth understanding of the Au morphology on the TiO templates is achieved with grazing-incidence small-angle X-ray scattering (GISAXS) during the sputter deposition. The resulting Au nanostructure is largely influenced by the TiO template morphology. Based on the detailed understanding of the Au growth process, characteristic distances can be selected to achieve tailored Au nanostructures at different Au loadings. For selected sputter-deposited Au/TiO hybrid thin films, the optical response with a tailored localized surface plasmon resonance is demonstrated.
