Thermal Emission In article number 2100545, Yeongseon Kim, Chanhee Kim, and Myeongkyu Lee employ layer‐by‐layer laser printing to selectively and dynamically control the thermal emissivity of a phase‐change GST emitter. This method can produce gradient emission patterns as well as stepwise patterns, enabling long‐IR emissivity at a specific position to be tuned from 0.26 to 0.8. The presented approach is promising for IR‐adaptive camouflage and security.
