Practical applications of phosphor particles in light sources and displays generally require the adhesion and support of polymer materials. However, these phosphor/polymer composites suffer from the difficulty in self-repairing after fracture. Inspired by the development of self-healing polymers, herein, we prepared phosphor/polymer composite films with self-repairing and restructuring properties. The N,N-dimethylformamide dispersant was used to uniformly disperse the phosphor particles in the self-healing polymer, which is considered to the key process for obtaining self-repairing properties. The developed self-repairing composite films are particularly suitable for restructuring luminescent patterns to provide multidimensional light-emitting modes including photoluminescence, persistent luminescence and mechanoluminescence. These results are expected to provide new insights for designing multifunctional self-repairing and reconstructing composites for anti-counterfeiting, integrated optics, optical communications, and artificial skins.
