摘　　要：电沉积ＷＯ３薄膜显示出可逆光致变色及电致变色行为（在红外区域附近具有蓝色光吸收）。通过Ｘ射线光电子能谱（ＸＰＳ），对ＷＯ３薄膜在不同呈色水平上的Ｗ４ｆ核能级作了观察研究，可见Ｗ４ｆ核能级在ＷＯ３膜显色后变宽，光电化学测定表明ＷＯ３薄膜具有低光电转换效率。Electrodiposited WO 3 film exhibits reversible photochromism and electrochromism (blue light absorption appears around the infrared area) The film's W4f nuclear energy level on different color lever is observed through XPS and the results show that after color development the range of W4f nuclear energy level becomes wider Photo electrochemical test results show that the film possesses a lower photoelectric transformation efficiency (14 refs )
