摘要

Tungsten oxide (WO_3) is one of the most promising materials for electrochromic devices and is currently investigated for applications in catalysis, ferroelectricity and in sensor technology. Here a molecular assembly approach to synthesize by sol-gel meso and macroporous thin films of tungsten oxide using polyethylene-glycol as a templating agent is reported. Micro-Raman spectroscopy has been employed to investigate the structure of WO_3 thin films, deposited by dip-coating on glass, as a function of thermal annealing. This modified sol-gel route promotes the coexistence of a sub-stoichiometric monoclinic phase (most probably the WO2.72 phase) together with some hydrous phases (WO_3·nH_2O) even in samples heat treated up to 500 ℃.
