Abstract
PURPOSE: To produce the electrochromic electrode of superior display characteristics, mechanical strength, etc. by oxidizing the noble metal thin film provided on a substrate in an atmosphere containing oxygen, then reducing the same electrochemically.
CONSTITUTION: The iridium metal layer 3 formed through vapor deposition on a substrate 1 by way of a PbO layer 2 provided for the purpose of adhesiveness improvement is heated for about several minutes at about 850°C in an atmosphere containing oxygen to form oxide film of black color, thence this is cooled, after which it is hydrogen-reduced for several minutes at about -0.5V in an H-type cell for electrochemistry by using a H2SO4 solution (concentration about 1N). Here, it is also possible to produce the electrochromic electrode in the similar manner by using noble metals, such as Pt, Ru, Pd, and Os other than the above-mentioned iridium.
