We fabricated a complementary electrochromic device (ECD) by using water-dispersible nanoparticles (NP) of Prussian blue (PB) and WO₃ by using a wet process, which involved just coating. Although the ECD had a thick WO₃ film, it showed much higher contrast compared to other techniques. In addition, the ECD also showed fast optical switching speed and high durability over 100 cycles because of wettability control of NP inks.

使用含有 WO3 和普鲁士蓝纳米粒子的水基墨水绿色制造互补电致变色器件

我们通过使用仅涉及涂层的湿法工艺使用普鲁士蓝 (PB) 和 WO _{3的水分散性纳米颗粒 (NP) 制造了互补电致变色器件 (ECD)。}尽管 ECD 具有较厚的 WO ₃膜，但与其他技术相比，它显示出更高的对比度。此外，由于 NP 墨水的润湿性控制，ECD 还显示出快速的光学切换速度和超过 100 次循环的高耐久性。
