    Abstract

    We propose a simple five-layer structure for creating red structural color, which has high color purity and high brightness. The design is based on the superposition of a silver substrate and multilayer silicon material. Absorption at the shorter wavelengths of the structure is effectively guaranteed, and reflection at the longer wavelengths is well enhanced. The red structural color has a peak reflectivity of 91% and a colorimetric purity of 0.9. Moreover, the designed structure displays angle-invariant performance up to 60°. This kind of structure scheme is environmentally friendly with low fabrication cost, and it can play an important role in a variety of fields, such as color displays and image sensors.
