摘　　要：研制了集电致变色和透明导电功能为一体的MoO_3/Ag/MoO_3(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12.2Ω/□。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11.1s),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 cm^2·C^(-1)),在已报道的MoO_3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/口. 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.
