Abstract

The photochromic and thermochromic properties of molybdenum oxide (MoO ₃) thin films doped with zinc selenide (ZnSe) were studied. The films were deposited on glass substrates by thermal evaporation of MoO ₃-ZnSe powder mixtures. EDS measurements confirmed the incorporation of ZnSe in the MoO ₃ matrix while MicroRaman spectra of the samples showed structural changes by increasing ZnSe. MoO ₃ films doped with 5 mol ZnSe presented an enhancement in the photochromic effect compared to the undoped MoO ₃ samples. The thermochromic effect was most pronounced for 5 mol ZnSe samples annealed at 23-125 °C, and for undoped samples annealed at 125-225 °C. The MoO ₃ films doped with 10 mol showed neither photochromic nor thermochromic effect.
