Embodiment Construction

[0010] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0011] The present invention provides a reflective film according to an embodiment, which contains silver, palladium and a rare earth element, and the rare earth element is selected from La and / or Yb.

[0012] It can be seen from the above scheme that by adding rare earth elements La and / or Yb to the alloy of metal silver and metal palladium, the anti-discoloration and anti-sulfurization capabilities of the reflective film are effectively improved.

[0013] In a specific implementation, the content of silver is 95-97wt%, and the content of palladium is 2-4wt%.

Abstract

The invention provides a silver alloy reflection film, and an electrochromic device provided with the same, which include silver, palladium and rare earth element. The rare earth element is selected from La and/or Yb. The silver alloy reflection film, and the electrochromic device provided with the same can effectively improve resistance of the reflection film to discoloration and sulfurization.

Description

technical field [0001] The invention belongs to the field of electrochromic devices, in particular to a silver alloy reflective film and an electrochromic device with the reflective film. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an external electric field, and the appearance is manifested as reversible changes in color and transparency. Materials with electrochromic properties are called electrochromic materials, and devices made of electrochromic materials are called electrochromic devices. The electrochromic devices mainly include electrochromic smart dimming glass, electrochromic display , Car automatic anti-glare rearview mirror. [0003] At present, silver alloy reflective film is usually used as electrochromic material, which is applied in electrochromic devices, but the existing silver...
