This paper investigates the color characteristics of Al-ZrO2-SiO2 plasmonic linear gratings, particularly focusing on the trade-off between the purity of the surface plasmon resonance induced color and the transmission efficiency. In our proposed plasmonic color filter, the factor that determines the resonance wavelength is the grating period, and the main factor controlling the relationship between color purity and transmittance is the grating fill factor, i.e. duty ratio. This means that the bandwidth of the transmittance spectrum can be tuned using the fill factor. Its physical reasoning is described. A full-color pallet is fabricated in the form of an Al-ZrO2-SiO2 linear grating with a fixed thickness and adjusted pairings of the grating period and fill factor. [ABSTRACT FROM AUTHOR] |
