Most multispectral compatible infrared camouflage devices primarily focus on achieving low emissivity but neglect environmental emissivity matching when environmental emissivity exceeds that of the devices, this creates a "low-emissivity exposure" risk. To address this issue, we develop a tunable multispectral compatible infrared camouflage device using phase change material In3SbTe2 (IST).
Simulation and experimental results demonstrate that in both the amorphous (aIST) and crystalline (cIST) states, the device achieves simulated plant infrared camouflage and ultra-low emissivity infrared camouflage within the atmospheric window bands (3–5 µm and 8–14 µm). To address thermal management, it utilizes two non-atmospheric window bands (2.5–3 µm and 5–8 µm) for heat dissipation. Additionally, laser stealth is realized at three specific wavelengths (1.064 µm, 1.55 µm, and 10.6 µm).
In the visible spectrum, high absorptivity enables effective visible light camouflage. Adjusting the geometric parameters of top layer structure enables color variation. This work not only highlights potential applications in reversible switching, reconfigurable imaging, and dynamic coding using IST but also offers an effective strategy to counter multispectral detection technology.
