Plasmonic Color Filter and its Fabrication for Large‐Area Applications

A large plasmonic color filter (PCF) is fabricated via a simple and cost‐effective method. The aluminum surfaces are surrounded by lithium fluoride with the penetration depth scaled to match the surface plasmon modes efficiently, resulting in high transmittance. All filters of primary colors show pe...

Zusammenfassung:A large plasmonic color filter (PCF) is fabricated via a simple and cost‐effective method. The aluminum surfaces are surrounded by lithium fluoride with the penetration depth scaled to match the surface plasmon modes efficiently, resulting in high transmittance. All filters of primary colors show peak transmittance at the wavelength regions corresponding to those determined in calculations.
