Abstract
Electrochromic niobium oxide thin films were prepared by chemical vapo r deposition. The source material was niobium (V) ethoxide. Amorphous niobium oxide thin films were obtained at a substrate temperature 350- degrees-C. Reduction and oxidation of the films in a 0.1M Na2CO3 + 0.1 M NaHCO3 buffer solution resulted in desirable changes in optical abso rption. Coulometry indicated that the coloration efficiency was 160 cm 2. C-1.
