New types of photochromic and electrochromic devices and solutions contained within them are provided. The new type photochromic devices constructed with TiO2 layers on either clear glass or ITO glass sheets and on either one side or two sides inwardly can color when the devices are exposed to sunlight or illuminated by a xenon lamp and bleaches again when they are put into dark or the daylight at an indoor. The coloring and bleaching processes occur in a few minutes and are reversible. The new electrochromic devices constructed with a TiO2 thin layer on an ITO glass sheet as one electrode provide good electrochromic performances. The photochromic and electrochromic devices of the present invention are stable to cycling between colored and bleached states. They can be used as variable transmission light filters, as smart windows, as displays, as mirrors, as UV radiation detectors or indicators, as sunlight glasses or sunroofs.
提供了新型光致变色和电致变色装置及其所含的解决方案。新型光致变色装置在透明玻璃或 ITO 玻璃片上单面或双面向内铺设了 TiO2 层,当装置暴露在阳光下或在氙灯照射下时可以着色,而当装置置于黑暗或室内日光下时又会漂白。着色和漂白过程在几分钟内完成,并且是可逆的。新的电致变色装置是在 ITO 玻璃片上以 TiO2 薄层为一个电极而制成的,具有良好的电致变色性能。本发明的光致变色和电致变色器件可在有色和漂白状态之间稳定循环。它们可用作可变透射率滤光器、智能窗户、显示器、镜子、紫外线辐射探测器或指示器、日光眼镜或天窗。
