在智能窗应用的开关镜薄膜的研究中，钯盖帽镁钛薄膜的直流磁控溅射制备。研究了它们的光学性质、开关耐久性和晶体结构。我们表明，Pd/Mg-Ti薄膜具有特定的厚度是完全的颜色中性的透明状态和其光开关性能是适合于建筑和汽车车窗玻璃的应用。用原位X射线衍射方法研究了Mg（1-x）Ti_x薄膜在4%氢气负载下的三元结构。由于掺杂金属Ti的催化作用，Pd/Mg（1-x）Ti x薄膜开关镜与Pd覆盖的纯Mg薄膜相比显示出快速的吸氢和放氢动力学。
In an investigation of smart-window applications of switchable mirror thin films, Pd-capped magnesium-titanium thin films were prepared by dc magnetron sputtering. Their optical properties, switching durability and crystalline structures have been investigated. We show that Pd/Mg-Ti thin films with specific thicknesses are completely color-neutral in the transparent state and their optical switching properties are suitable for building and automobile window glass applications. The ternary hydrides of Mg(1-x)Tixthin films with Pd overlayers are identified byin situX-ray diffraction measurements during a hydrogen gas loading of 4%. Pd/Mg(1-x)Tixthin film switchable mirrors show fast hydriding and dehydriding kinetics as compared to a Pd-capped pure Mg thin film due to the catalytic role of doped metallic Ti.
