Title:
MULTI-COLOR ELECTROCHROMIC STRUCTURE HAVING HIGH BRIGHTNESS, SATURATION AND PURITY, MULTI-COLOR ELECTROCHROMIC DEVICE, AND METHOD FOR PREPARING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/061953
Kind Code:
A1
Abstract:
Disclosed in the present application are a multi-color electrochromic structure having a high brightness, saturation and purity, a multi-color electrochrmic device, and a method for preparing the structure. The multi-color electrochromic structure comprises an electrochromic layer, which comprises a plurality of layer number pair structures formed by sequentially and alternately superposing and arranging first optical structure layers or second optical structure layers and dielectric layers, wherein bonding interfaces of the dielectric layers and the first optical structure layers and of the dielectric layers and the second optical structure layers are respectively first surfaces and second surfaces of the dielectric layers, and the first surfaces and the second surfaces are fitted with the dielectric layers to form optical cavities. Further disclosed in the present application is the multi-color electrochromic device. In the present application, metal layers of different thicknesses or dielectric layers of different thicknesses are deposited on different substrates to serve as electrochromic structures, such that the multi-color electrochromic structures having different brightnesses, saturations and purities can be realized. The multi-color electrochromic structure of the present application belongs to structural colors, is stable in color, is brightly colored and has a high degree of manufacturability, and cannot age or lose color after being exposed to an outdoor environment for a long time.
