摘要: Color filters in different surroundings inherently suffer from angular sensitivity, which hinders their practical applications. Here, we present an angle-insensitive plasmonic filter that can produce different color responses to different surrounding environments. The color filters are based on a two-dimensional periodically and randomly distributed silver nanodisk array on a silica substrate. The proposed plasmonic color filters not only produce bright colors by altering the diameter of the Ag nanodisk, but also achieve continuous color palettes by changing the surrounding environment. Due to the weak coupling between the metallic nanodisks, the plasmonic color filters can enable good incident angle-insensitive properties (up to 30°). The strategy presented here could exhibit robust and promising applicability in anti-counterfeiting and imaging technologies.
