VO2相变温度及性能的影响因素与应用研究进展

Progress in Factors influencing Phase Transition Temperature and Properties of VO2 and its Applications

摘要:

二氧化钒（VO2）作为一种相变金属氧化物，相变温度为68℃。在68℃以下VO2呈绝缘单斜相，在68℃以上呈金红石相，由于这种晶体结构的变化导致VO2在光性能和电性能方面表现出可逆的突变，从而成为光电开关领域的宠儿。基于此，本文对VO2的制备方法及其调控VO2相变温度与性能所采取的主要手段进行了综述，并归纳了不同制备方法的优缺点及调控VO2相变温度与性能的因素，总结了近年来VO2的应用进展，最后对VO2今后的发展趋势进行了展望，期望对相关领域的研究者具有指导作用。

Abstract:

As a phase transition metal oxide, the phase transition temperature of vanadium dioxide (VO2) is 68℃. VO2 presents an insulating monoclinic phase below 68?C and a rutile phase above 68?C. Because of the change in crystal structure, VO2 exhibits reversible mutations in optical and electrical properties, thus becoming a darling in the field of photoelectric switches. Based on this, this paper reviewed the preparation methods of VO2 and the main measures taken to regulate the phase transition temperature and performance of VO2. The advantages and disadvantages of different preparation methods and the factors that regulate the phase transition temperature and performance of VO2 were generalized. The application progress of VO2 in recent years was also summarized. Finally, the future development trend of VO2 was prospected. It was expected to provide guidance for researchers in related fields.
