Design of Reflective Tunable Structural Color Metasurface Based on Guided-Mode Resonance Filter and Sb2S3

In recent years, dynamically tunable structural color has attracted great interest. Here, we introduce the guided-mode resonance (GMR) filter and phase-change material Sb2S3 to design a reflective optical metasurface produce color, in which combination of GMR filter, with narrow resonant wavelength, Sb2S3, much larger bandgap higher refractive index, helps high-quality color. The simulation results indicate that through phase transition between amorphous crystalline states proposed can generate be perceived by naked eye. Furthermore, sensitively sense environmental changes This work provides new method for realizing paves way application controllable dynamic displays, stealth, colorimetric sensing, other fields.
