研制了集电致变色和透明导电功能为一体的MoO3/Ag/MoO3 (MAM)双功能薄膜。MAM薄膜采用电子束热蒸发技术在室温下制备。作为透明电极，MAM薄膜显示出良好的光电性能，可见光平均透过率为59.4%，方块电阻为12.2 Ω/□。作为电致变色材料，MAM薄膜具有较快的响应时间(着色时间4.3 s，褪色时间11.1 s)，25%的光学对比度(528 nm)，良好的稳定性(100次循环)，以及较高的着色效率(40.5 cm2·C-1)，在已报道的MoO3着色效率中处于较高的水平。

MoO3/Ag/MoO3 (MAM) films were utilized for constructing bi-function electrochromic devices, which served as both transparent electrodes and electrochromic materials. MAM films were prepared by E-beam evaporation at room temperature. As a transparent electrode, MAM film has a good photoelectric performance with an average transmittance of 59.4% and a sheet resistance of 12.2 Ω/□. As an electrochromic material, MAM film shows a fast response time (coloration time 4.3 s, bleaching time 11.1 s), a larger optical contrast of 25% at 528 nm, a good stability (100 cycles) and a higher coloration efficiency of 40.5 cm2·C-1, which is at a high level among the reported data.
