Abstract
Extraordinary Optical Transmission Plasmonic Color Filters (EOT-PCFs) with nanostructures
have the advantages of consistent color, small size, and excellent color reproduction, making
them a suitable replacement for colorant-based filters. Currently, the color gamut created by plasmonic
filters is limited to the standard red, green, blue (sRGB) color space, which limits their use
in the future. To address this limitation, we propose a surface plasmon resonance (SPR) color filter
scheme, which may provide a RGB-wide color gamut while exceeding the sRGB color space. On the
surface of the aluminum film, a unique nanopattern structure is etched. The nanohole functions as a
coupled grating that matches photon momentum to plasma when exposed to natural light. Metals
and surfaces create surface plasmon resonances as light passes through the metal film. The plasmon
resonance wavelength can be modified by modifying the structural parameters of the nanopattern
to obtain varied transmission spectra. The International Commission on Illumination (CIE 1931)
chromaticity diagram can convert the transmission spectrum into color coordinates and convert the
spectrum into various colors. The color range and saturation can outperform existing color filters.
