Modified electrochromism of tungsten oxide via platinum nanophases
View through CrossRef
We report electrochromic properties of WO3 modified by platinum nanophases. The WO3 incorporated by Pt metallic nanophases (Pt–WO3) showed exactly reverse electrochromic phenomenon compared with that of both pure WO3 and WO3 intercepted and coated by metallic Pt thin-film layer. In addition, to investigate the origin of modified electrochromic properties, electrodes consisting of WO3 and/or Pt layers were designed and observed in optical properties during electrochemical reaction. The change of electrochromic properties in the Pt–WO3 is caused by modified structural and electrochemical properties of the WO3 by Pt metallic nanophases dispersed in the oxide matrix.
