Abstract采用掠射角反应磁控溅射法在室温下沉积了纳米结构氧化钨(WO3)薄膜,并对薄膜进行热处理。利用场发射扫描电镜(FE-SEM)和X射线衍射仪(XRD)对氧化钨薄膜的形貌和结构进行了表征。当掠射角度为80?时,采用直流电源沉积的氧化钨薄膜具有纳米斜柱状结构,而采用脉冲直流电源沉积的薄膜呈现纳米孔结构。纳米薄膜经450℃热处理3h后,纳米斜柱彼此连接,失去规整结构,而纳米孔结构的孔尺寸变大。XRD分析表明室温沉积的氧化钨薄膜具有无定形结构,经450℃热处理1h后,转变为单斜晶相。具有纳米斜柱状或纳米孔结构氧化钨薄膜的光学调制幅度在波长600nm时达到60%,且电致变色性能可逆。
Other AbstractNano-structured tungsten oxide (WO 3 ) thin films were deposited at room temperature by glancing anglereactive magnetron sputtering and then annealed at 450℃ in air. The films were characterized by field-emissionscanning electron microscope (FE-SEM) and X-ray diffraction (XRD). The WO 3 thin film deposited by DC magnetron sputtering at 80° glancing angle exhibited oblique nano-column structure, while deposited by pulsed DC magnetron sputtering at the same angle exhibits nano-pore structure. After annealing at 450℃ for 3 h, the obliquenanocolums are conjunct with each other but the nano-pore structured remains with bigger pore size. XRD analysisreveals that WO 3 thin films deposited at room temperature demonstrate amorphous structure. The amorphous structure will transfers to monoclinic phase after annealing at 450℃ for 1 h. Transmittance difference between colorization and bleaching of nano-structured WO 3 thin film reaches 60% at wavelength of 600 nm. Electrochromic properties of nano-structured WO 3 thin films are highly reversible.
