Abstract: Nanocrystralline TiO2 semiconducting electrode was prepared by using a screen-printing technique. The electrode has very high specific surface-to-volum area which is crucial for the absorption of
more chromophores on the surface. The electrochromic device was assembled by using a sandwich structure after the electrode absorbed chromophore molecules. The electrochromic device was
characterized by UV-Vis spectra. The electrochromic device has a very high transparency at its bleached states (85%), and deep violet at its colored states (4%), which has potential use in smart window, flat
panel display, electric book and electric papers.

Key words: screen-printing technique, nanocrystralline, TiO2, electrochromic
