<p>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.</p> |
