description

The influence of exposure in vacuum of 10-2 - 10-3 Pa and temperature treatment at 720 - 730 K in water vapor atmosphere on stability of tungsten oxide films in 0.1 N H2SO4 electrolyte were studied. The processes that take place during the film exposure in vacuum, determine the reduction of charge injection at the constant voltage change condition. In the case of temperature treatment the opposite changes of charge injection were observed. This indicates to opposite processes in films during both expositions. According to exposures characters, they could be a reduction of tungsten oxide initiated by oxygen evacuation from film in vacuum and film oxidation in water vapor media at high temperature. The other processes during exposure time in vacuum, high temperature and electrolyte, are discussed.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
