利用慢正电子束流技术和X射线光电子能谱研究了热致变色和电致变色三氧化钨(WO_3)薄膜中W离子在膜内和表面的分布。结合其变色性能,讨论了热致变色和电致变色之间的相关性。
The distributions of W ions in the thermochromic and electrochromic tungsten trioxide (WO_3) thin films on and in the film were studied by slow positron beam current and X-ray photoelectron spectroscopy. In combination with its color changing properties, the correlation between thermochromism and electrochromism was discussed.
