Abstract
This paper reports a high-performance organic light-emitting paper-based flexible anticounterfeiting (FAC) device with multiple stimuli-responsiveness (light, electricity, and their combination). The FAC device is fabricated by integrating patterned electro-responsive and photo-responsive organic emitters onto paper substrates, preserving pre-existing security information. Optical microcavities enable noticeable color shifts with varying viewing angles and applied voltage. The device is bendable, unclonable, and durable (half-lifetime over 4000 hours at 100 cd m⁻²).
