摘要：

Tungsten oxide (WO3) is one of the most promising materials for electrochromic devices. WO3 thin films have been prepared at low temperature by using a polyethylene glycol (PEG) assisted sol-gel method. The structure and the stoichiometry of films deposited by dip coating on glass substrates have been studied as a function of thermal annealing by XRD, FTIR and mu-Raman. PEG-containing samples show improved electrochromic efficiency due to the formation of sub-stoichiometric, nanocrystalline phases. The electrochromic performance of WO3 films gets worse for annealing temperatures higher than 300 degreesC due to massive Na absorption from the substrate. (C) 2004 Elsevier B.V.
