金/二氧化钛（Au/TiO 2）纳米杂化材料因其优异的光学和光催化性能而在各个领域得到了广泛的应用。通过最先进的聚合物模板，可以用潜在的大规模加工方法制备均匀的纳米结构TiO 2层。我们使用定制的聚合物模板，以实现不同形貌的二氧化钛纳米结构。采用溅射沉积法制备了Au/TiO 2杂化薄膜。在溅射沉积过程中，在原位掠入射小角X射线散射（GISAXS）内实现TiO 2模板上的Au形态的深入理解。所得到的Au纳米结构在很大程度上受到TiO 2模板形貌的影响。基于对Au生长过程的详细理解，可以选择特征距离以在不同Au负载下实现定制的Au纳米结构。对于选定的溅射沉积的Au/TiO 2杂化薄膜，与定制的局部表面等离子体共振的光学响应被证明。
Gold/titanium dioxide (Au/TiO2) 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 TiO2layers with potentially large-scale processing methods. We use customized polymer templating to achieve TiO2nanostructures with different morphologies. Au/TiO2hybrid thin films are fabricated by sputter deposition. An in-depth understanding of the Au morphology on the TiO2templates is achieved within situgrazing-incidence small-angle X-ray scattering (GISAXS) during the sputter deposition. The resulting Au nanostructure is largely influenced by the TiO2template 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/TiO2hybrid thin films, the optical response with a tailored localized surface plasmon resonance is demonstrated.
