Optical properties of electrochromic hydrated nickel oxide coatings made by rf sputtering

Electrochromic NiO(x)H(y) coatings were produced by rf magnetron sputtering of Ni in the presence of H(2) and O(2) followed by treatment of the films in KOH. Spectral transmittance and reflectance were measured in the 0.35 </= lambda </= 2.5-microm wavelength range. The integrated luminous and...

Summary:Electrochromic NiO(x)H(y) coatings were produced by rf magnetron sputtering of Ni in the presence of H(2) and O(2) followed by treatment of the films in KOH. Spectral transmittance and reflectance were measured in the 0.35 </= lambda </= 2.5-microm wavelength range. The integrated luminous and solar transmittance could be varied between approximately 75 and 10% and between approximately 75 and 20%, respectively. Electrochromic coloration was found to be associated with the formation of a broad absorption band centered at lambda approximately 0.8 microm.
