Abstract

Infrared camouflage technology has received considerable attention for escaping the tracking by an infrared detector. The phase-changing material Ge2Sb2Te5 (GST) has widely been utilized to design dynamic spectral regulation. Herein, we propose a planar selective emitter based on the GST with different phases to simultaneously realize infrared camouflage and radiative heat dissipation. The fabricated emitter demonstrates a low emissivity of 32.6% inside the atmospheric windows and a high emissivity of 67.8% outside the atmospheric windows due to the formed quasi-optical cavity of the GST and the metal Ni layer in the structure. Moreover, it also has the potential to be used in different conditions by controlling the emission peak position. The facile process technique allows scalable production and large-scale deployment of the proposed emitter.
