为新型智能窗的基础研究，制备了全固态Mg-Ni薄膜可切换反射镜。该装置具有多层Mg-Ni/Pd/ ta2o5 / wo3 /氧化铟锡/玻璃，并且可以从反射状态可逆地切换到透明状态。通过循环开关试验研究了该器件的耐久性。虽然透射率变化略有下降，但该器件显示出高达2000次开关循环的高耐用性。我们发现这种降解与Mg-Ni薄膜表面的损伤以及在循环开关测试中Ni和Pd原子扩散到ta2o5薄膜中有关。
An all-solid-state switchable mirror with Mg-Ni thin film was prepared for basic research on a new type of smart window. The device has a multilayer of Mg-Ni/Pd/Ta 2 O5/WO 3 /indium tin oxide/glass and can switch reversibly from a reflective state to a transparent one. The durability of the device was investigated by a cyclic switching test. Though a transmittance change was slightly decreased, the device showed high durability up to 2000 switching cycles. We found that the degradation was related with the damaged surface of Mg-Ni thin film and the diffusion of Ni and Pd atoms into Ta 2 O 5 thin film during a cyclic switching test.
