Electrochromism stands out as a highly promising technology for applications including variable optical attenuators, optical switches, transparent displays, and dynamic windows. The pursuit of high-contrast tunability in electrochromic devices remains a challenging goal. Here, the first photochromic hydrogel electrolyte is reported for electro- and photo-dual responsive chromatic devices that yield a high transmittance contrast at 633 nm (ΔT = 83.1%), along with a tinted transmittance below 1.5%. Such high-contrast devices not only hold great promise for dynamic windows but also enable seamless transitions between transparent augmented reality (AR) glass and opaque virtual reality (VR) glass. These findings introduce an innovative strategy for the design of high-contrast dimmers, opening new avenues for the development of chromatic devices.
电致变色作为一种极具前景的技术，应用于可变光衰减器、光开关、透明显示器和动态窗户等领域。在电致变色器件中追求高对比度可调性仍然是一个具有挑战性的目标。在此，报道了首个用于光电双响应变色器件的光致变色水凝胶电解质，该器件在633 nm处具有高透过率对比度（ΔT = 83.1%），同时着色透过率低于1.5%。这种高对比度器件不仅在动态窗户方面具有巨大潜力，还能实现透明增强现实（AR）玻璃和不透明虚拟现实（VR）玻璃之间的无缝过渡。这些发现为高对比度调光器的设计引入了一种创新策略，为变色器件的发展开辟了新途径。
