Anti‐Smudge Organic Afterglow Panels

Abstract Organic afterglow panels show promising applications in display and information anti‐counterfeiting. Like other panels, organic afterglow panels are susceptible to contamination when used, which can affect their aesthetics and clarity. Here, a kind of visible‐light‐excitable anti‐smudge organic afterglow panels based on a dopant‐matrix strategy and easily prepared through the UV light‐curing method is reported. The phosphorescence lifetime of the panel is up to 9.45 s with an afterglow duration longer than 100 s. Moreover, the transparent panels with low dynamic friction (0.129), large water contact angle (108°) and oleic acid contact angle (77°), display high performance of anti‐smudge, water and oil repellency, and removability of fingerprints, avoiding the influence of ink or sewage on its aesthetics and clarity. This study will expand the pathways for practical applications of afterglow materials.
