    This study introduces angle-insensitive plasmonic color filters using randomly distributed silver nanodisks. These filters offer stable, reproducible colors for digital imaging and sensing applications.

    Area of Science:

    • Nanophotonics and Plasmonics
    • Optical Materials Science

    Background:

    • Plasmonic color filters typically exhibit angular sensitivity, limiting their practical use.
    • Existing filters often rely on periodic structures, which can be complex to fabricate and sensitive to defects.

    Purpose of the Study:

    • To develop an angle-insensitive plasmonic subtractive color filter.
    • To demonstrate stable and reproducible color generation using localized surface plasmon resonances (LSPRs).

    Main Methods:

    • Fabrication of a color filter using two-dimensional randomly distributed silver nanodisks on a glass substrate.
    • Characterization of the filter's optical properties, focusing on angle dependence and color tunability.
    • Utilizing localized surface plasmon resonances (LSPRs) for color generation.

    Main Results:

    • Achieved excellent angle-insensitive performance up to 60 degrees.
    • Demonstrated stable and reproducible colors due to uncoupled LSPRs.
    • Obtained a wide palette of colors across the visible spectrum by varying nanodisk diameter.

    Conclusions:

    • The proposed random nanodisk plasmonic color filter overcomes inherent angular sensitivity.
    • The filter shows robust applicability in digital imaging and sensing industries due to its stability and tunability.
