C. Natarajan et G. Nogami, CATHODIC ELECTRODEPOSITION OF NANOCRYSTALLINE TITANIUM-DIOXIDE THIN-FILMS, Journal of the Electrochemical Society, 143(5), 1996, pp. 1547-1550
A new technique for depositing nanocrystalline titanium dioxide thin f
ilms on electronically conducting glass was developed. This technique
is a two-stage process: (i) cathodic electrodeposition of titanium oxy
hydroxide gel film from aqueous solution containing a Ti precursor and
(ii) subsequent heat-treatment of this gel film results in the format
ion of titanium dioxide film. The deposition potential may have a cons
iderable effect on the formation of nanocrystalline film. The nanocrys
talline titanium dioxide film shows reversible electrochromism in lith
ium-ion-containing organic electrolyte. The coloration and bleaching t
hroughout the visible and near-IR range can be switched on and off wit
hin a few seconds.
