摘要
二氧化钒薄膜在68℃附近发生绝缘-金属相变时,光学性能(尤其是红外部分的光学性能)发生显著突变。这一优异的热色性能使得二氧化钒薄膜在智能窗领域具有潜在的应用价值,并已成为该领域的研究热点。然而,二氧化钒薄膜存在太阳能调制效率较小、可见光透过率较低、相变温度偏高、热稳定性不高等缺点,这大大限制了它的实际应用。为了解决这些问题,研究人员开展了广泛而深入的工作。从主要制备方法(磁控溅射法、化学气相沉积法、溶胶-凝胶法和水热法)和提高热色性能的方法(掺杂、多层膜及复合膜)等方面对二氧化钒薄膜热色性能的研究进行了综述和分析,以期为氧化钒薄膜及智能窗等领域的研究人员提供参考。
Vanadium dioxide thin film undergoes an insulator-metal phase transition at about 68 ℃, which is accompanied by an abrupt and large change of optical properties especially in the infrared region. Vanadium dioxide thin films have a potential application in smart windows due to the above unique thermochromic property. As a result, vanadium dioxide thin films have become a hot research topic in smart windows. However, several drawbacks such as small solar modulation ability, low luminous transmittance, high phase transition temperature,and undesirable thermochromic stability have hindered the practical applications of vanadium dioxide thin films in smart windows. In order to solve these issues, great efforts have been made by researchers in recent years. This review focuses on the important preparation methods(magnetron sputtering method, chemical vapour deposition method, sol-gel method, and hydrothermal method) and the strategies for improving the thermochromic properties(doping, multilayer films, and composite films). We hope that this review can provide references to the researchers who investigate the thermochromic properties of vanadium dioxide films as well as smart windows.
