Abstract

In this study, an all-thin-film inorganic electrochromic device was monolithically fabricated on a 10 cm x 8 cm flexible PET/ITO substrate by magnetron sputtering process at room temperature. The device has a complementary structure and consists of five thin films. Tungsten oxide (WO₃) and nickel oxide (NiO_x) act individually as complementary electrochromic layers. Lithium tantalate (LiTaO₃) plays the role of Li⁺ ions conductor layer and both indium tin oxides (ITO) are adopted as inter-counter transparent conductive electrodes. The complementary device with con figuration ITO/NiO_x /LiTaO₃/WO₃/ ITO has high optical modulation approximating 63% in the range from 400 to 1600 nm and shows the coloration efficiency as high as 68.5 cm² C^-1. In addition, the response characteristic is investigated for the electrochromic process.
