摘　　要：应用电沉积法制备WO3、NiO、M0O3、WO3/MO03等电致变色薄膜。WO3薄膜、NiO薄膜、M0O3薄膜具有较好的电致变色特性,漂白态和着色态的透射率之差平均为30%左右。WO3/M0O3掺杂薄膜漂白态和着色态的透射率之差平均为40%左右,显示掺杂有利于增强薄膜的电致变色特性。WO3+NiO互补型电致变色体系漂白态和着色态的透射率之差平均为40%左右,显示互补型电致变色材料有利于增强电致变色特性。在双注入模型的基础上,根据过渡金属配合物显色机理,提出解释电致变色机理的“配位场模型”,认为在电致变色中可能存在三种电子跃迁方式。WO3, NiO, MoO3, WO3/MoO3 electrochromic films were prepared by electrodeposition. WO3, NiO, MoO3 films whose different transmittances between bleached and coloured states are about 30% possess electrochromism. MoO3 doped WO3 film whose different transmittance between bleached and coloured states is about 40% displays better electrochromism. WO3 + NiO complementary system whose different transmittance between bleached and coloured states is about 40% displays better electrochromism. 'Coordination field model' about electrochromic mechanism is put forward based on 'double-charge injection model' and the chromogenic mechanism of transition metal complexes. 'Coordination field model' considers there may be three patterns of electronic transitions in electrochromism.
