The vanadium oxide system is simple and inexpensive because only a single-layer film of this material is sufficient for coloration. The film thickness. morphology, and crystal structure were determined by scanning electron microscopy and x-ray diffraction. The optical property was characterized by UV-Vis spectroscopy. The electrochemical properties were determined by cyclic voltammetry. The results show that the Mo-modified V2O5 thin film exhibits better coloration rate than as-made one which can be attributable to the changes of local atomic symmetry and electronic structure. In situ/operando X-ray absorption spectroscopy was used to track the evolution of atomic and electronic structures under electrochromic coloration to elucidate the color switching mechanism. This study may provide important process for the fabrication of electrochromic films for energy-saving windows or other useful electronic devices. Da-Hua Wei 魏大華 2018 學位論文 ; thesis 73 zh-TW |
