摘　　要：二氧化钒是一种热致变色材料,相变温度为68℃。相变前后二氧化钒光学性能有较大的变化,如二氧化钒对红外线透过率低温态时大,高温态时小。利用这一特点,在玻璃基体上沉积二氧化钒薄膜,可实现对汽车、建筑物、航天器等室内温度的自动调节,从而达到对太阳光能的智能化利用,节省地球能源。本文分析应用原理并且探讨相关问题。VO2 is a kind of thermochromatic material, whose metalsemiconducting phase transition temperature is 68℃. The optical property of VO2 will change a lot before and after the transition, such as the higher transmittance at low temperature and the lower transmittance at high temperature. Depositing VO2 film on glass to form smart window makes it possible to adjust automatically the temperature in automobiles, buildings etc. Thus intelligent use of the sun's energy can be achieved so as to save the energy of the earth. This article analyses the principle and discusses the related issues.
