【摘要】 采用中频孪生非平衡磁控溅射技术制备钛掺杂WO₃薄膜。运用X射线衍射（XRD）,拉曼光谱、紫外分光光度计、计时安培分析仪和原子力显微镜（AFM）等测试手段分析了钛掺杂WO₃薄膜的结构和光学性能。实验结果表明,掺杂后的薄膜在相同的热处理条件下晶化程度降低,晶粒细化,离子抽出和注入的通道大大增多,钛掺杂原子数分数0．051的着色响应速度提高,循环寿命提高了4倍以上,但着色后透射率下降。更多还原

【Abstract】 Ti-doped WO₃ films were prepared by mid-frequency dual-target magnetron sputtering method.The Ti-doped WO₃ films were characterized with X-ray diffraction （XRD）,Raman spectroscopy,ultraviolet spectrophotometer,chronoamperometry and atomic force microscopy （AFM） .The results indicate that after doping Ti,its crystallinity decreases at the same annealing temperature,and its surface roughness decreases dramatically with the increase of holes for ion injection and extraction,Accordingly,the response speed of the WO₃ film doped with fraction of atom number 0.051 of Ti is greatly improved compared with the undoped film,and its cycle life is increased more than four times,but the spectral transmittance decreases after doping.更多还原
