| Abstract |
WO3 thin films for electrochromic display (ECD) device were prepared by a spin-coating method from the organic tungsten solutions obtained by refluxing a mixture of tungsten hexachloride, a carboxylic... acid (typically n-butylic acid) and benzene. Amorphous WO3・H2O films were obtained when the spin-coated films were heat-treated at 100℃for 1 h. The electrochromic characteristics of the films depended on the carboxylic acids used for the starting solutions; n-Butylic acid gave a film having higher coloring and bleaching efficiency (injected charge of 4mC/cm2 for an optical density change of 0.5) as well as faster response (ca. 200 ms), as compared with those films obtained with acetic acid, propionic acid and none. SEM observation revealed that the film obtained with n-butylic acid was ca. 3μm thick and composed of small WO3 particles (ca. 0.1μm).show more
