“…By adjusting the relative thickness of the MMDM layers and their permittivities, the confinement of light of specific optical frequencies can be enhanced, thereby increasing the Q factor and realizing high-saturation colors. Although this approach can be used to obtain filters with high color purity, 26,27 to the best of our knowledge, no study has yet investigated MMDMs for EC devices. Herein, we propose and demonstrate a new type of MMDMstructured EC device based on periodic W−WO 3 stacks.…”

Inorganic electrochromic (EC) materials with vibrant multicolor change that are compatible with large-scale processing have been at the forefront of EC technology and are crucial in a wide range of applications, such as displays and camouflage. However, limited strategies are available to realize such inorganic materials, and challenges such as low color purity are yet to be overcome. Here, we demonstrate multilayered metal–dielectric metamaterials (MMDMs) as a new family of inorganics-based EC materials to achieve dynamic alternation among multicolors with high contrast and high color purity, which are structurally realized by significantly enhancing the confinement of the incident light in specific optical frequencies. This multilayer structure renders high reflectivity (75%), high quality factor (7.4), and a full width at half-maximum of 60 nm before coloration and presents a color gamut at least 40% wider than that of previously reported metamaterials after coloration, indicating good color quality.

In this study, an 11‐layer thin film with the thickness of 0.58 μm is designed to be placed under the red and green pixels. This film exhibits a blue light reflectance of 95% and a transmittance of 99% for red and green light. Additionally, the thickness of the RCF and GCF is reduced from the original 2 μm to 1 μm. Experimental results demonstrate a 19.9% increase in backlight transmittance and a color gamut reaching 118% sRGB.
