摘要：
The photochromic and thermochromic properties of molybdenum oxide (MoO3) thin films doped with zinc selenide (ZnSe) were studied. The films were deposited on glass substrates by thermal evaporation of MoO3-ZnSe powder mixtures. EDS measurements confirmed the incorporation of ZnSe in the MoO3 matrix while MicroRaman spectra of the samples showed structural changes by increasing ZnSe. MoO3 films doped with 5 mol% ZnSe presented an enhancement in the photochromic effect compared to the undoped MoO3 samples. The thermochromic effect was most pronounced for 5 mol% ZnSe samples annealed at 23-125 degrees C, and for undoped samples annealed at 125-225 degrees C. The MoO3 films doped with 10 mol% showed neither photochromic nor thermochromic effect.
