Abstract

The achievement of structural color has shown advantages in large-gamut, high-saturation, high-brightness, and high-resolution. While a large number of plasmonic/dielectric nanostructures have been developed for structural color, the previous approaches fail to match all the above criterion simultaneously. Herein we utilize the Si metasurface to demonstrate an all-in-one solution for structural color. Due to the intrinsic material loss, the conventional Si metasurfaces only have a broadband reflection and a small gamut of 78% of sRGB. Once they are combined with a refractive index matching layer, the reflection bandwidth and the background reflection are both reduced, improving the brightness and the color purity significantly. Consequently, the experimentally demonstrated gamut has been increased to around 181.8% of sRGB, 135.6% of Adobe RGB, and 97.2% of Rec.2020. Meanwhile, high refractive index of silicon preserves the distinct color in a pixel with 2 × 2 array of nanodisks, giving a diffraction-limit resolution.

  • Initial investigations into metasurface spectral filters used plasmonic metals, but there has been a gradual shift towards all-dielectric metasurfaces owing to their comparatively lesser optical absorption.

    “Initial investigations into metasurface spectral filters used plasmonic metals [8–13], but there has been a gradual shift towards all-dielectric metasurfaces (ADM) [14–17] owing to their comparatively lesser optical absorption.”

    The Introduction describes plasmonic structural color and all-dielectric structural color, and says some dielectrics are transparent in the visible, producing more vibrant colors. This supports the comparison in broad terms, but it does not document a gradual historical shift toward all-dielectric metasurfaces or establish lower absorption as the reason for that shift.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
