Abstract

This paper presents a novel bipolar information indication system inspired by fireflies, capable of indicating both changing and unchanging information without mutual interference. A photochemical afterglow material is integrated into a photonic crystal matrix using shear-induced ordering, enabling the system to display unchanging information via reflection color (under white light) and changing information via afterglow intensity (when light is off). The system is demonstrated as a smart label for photosensitive medicine, indicating both intrinsic drug information and its photodegradation level, offering a potential home-based solution for assessing medication efficacy.
