| ABSTRACT | Spectral decoupling concerns about selective modulation of specific regions over the wide electromagnetic spectrum, which is highly desirable for smart handling of light/heat, such as photo-thermal regulation, multiband camouflage, etc. However, effective spectral decoupling is still lacking, especially for independent control over non-adjacent bands with orders of discrepancy in wavelengths, e.g., visible and longwave infrared (LWIR). Herein, we demonstrate spectral decoupling regulator (SDR) based on a bilayer electro-optical resonator, which can be electrochemically reconstructed by targeted ion migration into the dielectric and reflective layers, respectively. The SDR is featured by switchable color presentation and wide-range LWIR regulation (with a ΔεLWIR of 0.57), consequently realizing a free re-combination between visible color and LWIR emissivity within single surface. The results demonstrate potentials for in-demand multispectral applications such as optical skin with visible/thermal modulation and encryption encoding information at different wavelengths. |
