article description
In this paper we studied switchable mirrors for application to transparent flat panel displays. The typical structure of switchable mirror has configuration of MgNi/Pd/TaO/HxWO/ITO. In this study photocatalyst layer (TiOor NbO) was used between Pd and TaOlayers. These layers were prepared by RF magnetron sputtering method utilizing TiOand NbOtargets under various conditions and their electrochromic properties were investigated by using FE-SEM, EDAX and Nano View system. The transmittances of the NbOand the TiOthin films, could be optimized in the switchable mirror as photocatalyst layer, where they were deposited under the power of 80 W and 70 W, respectively, by the RF magnetron sputter. The characteristics of NbOand TiOtransmittance are the outstanding at 80 W, 70 W respectively. Copyright © Taylor & Francis Group, LLC.
