Paper Abstract

This paper deals with the influence of near-surface region on electrochromic properties of sodium tungsten bronze (STB) crystals. The surface element analysis of STB was carried out by SIMS and ESCA methods. Effects of anodic polarization and electrochromic coloration-bleaching on the near-surface of crystals were investigated. It was found that anodic polarization resulted to extraction of sodium from near- surface region. This process is responsible for the appearance of uninterrupted channels which are permeable to hydrogen ions. Their mobility defines sensitivity of electrochromic structure based on STB crystal. Mechanisms of anodic polarization and electrochromic bleaching-coloration of NaxWO3 are discussed.
