采用直流磁控溅射法制备了具有45 ℃低温金属化转变温度的二氧化钒（VO 2）薄膜。原子力显微镜测量表明VO 2的晶粒尺寸约为100纳米。利用He-Ne激光功率强度测试仪对薄膜的红外特性进行了研究，结果表明VO 2薄膜具有良好的红外开关特性。此外，太阳能智能窗和激光防护实验表明，所获得的VO 2薄膜在相关领域的应用是一个有前途的材料。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4766287]
Vanadium dioxide (VO2) films with a low semiconductor-to-metal transition temperature of 45 degrees C were fabricated through direct current magnetron sputtering followed by a post-annealing. Atomic force microscopy measurements show that the VO2 grain size is about one hundred of nanometers. Infrared (IR) characteristic is well investigated by applying a He-Ne laser power intensity measurement, and the result reveals that the VO2 film exhibits excellent IR switching property. Furthermore, solar smart window and laser protection experiments demonstrate that the obtained VO2 thin film is a promising material for the application in related fields.
