Nanometer yellow tungsten oxide is a type of near infrared shielding material. Such material is what we often called heat insulation material. Yellow tungsten oxide nano powder is also an electrochromic material. After half a century of development, electrochromism has achieved many effective results and has been put into use in some fields. With the continuous development of science and technology, electrochromic materials and electrochromic devices will play a more important role.
At present, electrochromic glass (smart window) has been used in some high-end cars and aircraft. For example, nano grain size yellow tungsten oxide can be used to make automatic anti-glare rearview mirrors. Such anti-glare rearview mirror can adjust the intensity of the reflected light according to the intensity of the external light through the electronic induction system, to achieve the anti-glare effect and make driving safer. The electrochromic smart glass can adjust the light intensity inside the car and the aircraft with lower voltage and lower power, making the journey more comfortable.
