Abstract

We report electrochromic properties of W O3 modified by platinum nanophases. The W O3 incorporated by Pt metallic nanophases (Pt-W O3) showed exactly reverse electrochromic phenomenon compared with that of both pure W O3 and W O3 intercepted and coated by metallic Pt thin-film layer. In addition, to investigate the origin of modified electrochromic properties, electrodes consisting of W O3 and/or Pt layers were designed and observed in optical properties during electrochemical reaction. The change of electrochromic properties in the Pt-W O3 is caused by modified structural and electrochemical properties of the W O3 by Pt metallic nanophases dispersed in the oxide matrix.
