摘要
用直流磁控溅射法在玻璃基片上先沉积TiO2缓冲层,再用直流/射频反应磁控共溅射法制备掺钨VOX薄膜,然后在氮气中退火。用X射线衍射、原子力显微镜、紫外可见光分光光度计、红外光谱仪等对薄膜的结构、表面形貌、光透过率等进行测试分析。结果表明:在溅射气压为1 Pa,氧氩气体比例为1:4,Ti靶采用100 W直流电源时,所制备的TiO2缓冲层上的掺钨VOX薄膜致密,晶粒大小均匀。掺钨VOX薄膜样品的相变温度降低至35℃,可见光透过率较高,对红外光的屏蔽效果明显。
The TiO2 buffer layers were deposited on glass substrates by magnetron sputtering, next W-doped VOx thin films were deposited on them by direct current/radio frequency reactive magnetron co-sputtering, and then annealed in nitrogen atmosphere. The surface morphology, phase structure and light transmittance were investigated by atomic force microscopy, X-ray diffraction, ultraviolet visible spectrophotometer and infrared spectrometer. The results show that the prepared W-doped VOx thin film is compact with uniform grain size when the sputtering pressure is 1Pa, the ratio of oxygen to argon is 1:4, and Ti target DC power is 100W. At the same time the phase transition temperature of the sample is reduced to 35℃ with high light transmittance, and the shielding effect of infrared light is obvious.
