To investigate the microstructure of nickel oxide electrochromic films, cross-sectional observation of sputtered nickel oxide film was performed using a high resolution electron microscope. Lattice and atomic image could be observed for as-deposited sample and bleached sample. These images showed that crystallized NiO exists in both samples. As-deposited film contained small amount of Ni{sub 2}O{sub 3}. One of [111] axis shrank about 3% and the lattice was a little bit strained in bleached state. The fact that no trace of Ni(OH){sub 2} or other species was observed implies that the boundary and surface of NiO microcrystallites played an important role in the electrochromic reaction.
