Abstract
Persistent mechanoluminescence (PML) is highly desirable for its ability to overcome transient-emitting behavior, but its applications are hindered by the limited emission wavelengths. Herein, a universal chemical interlinkage-assisted efficient energy transfer (ET) strategy is introduced to achieve color conversion from green to red in traditional PML materials. A straightforward chemical route to create the RhB@SiO2/SAOED system is established via covalent chemical interlinkage by depositing mesoporous silica-encapsulated Rhodamine B (RhB) nanoparticles (RhB@SiO2) onto SrAl2O4:Eu, Dy (SAOED) particles. The resulting system exhibits a high ET efficiency of 53.5%. The multicolor PML of the RhB@SiO2/SAOED system remains visible to the naked eye for exceeding 28 s after mechanical stimulation. With this unique PML behavior, the RhB@SiO2/SAOED system demonstrates the potential applications ranging from visualized reading activities to multi-mode anticounterfeiting. This universal PML color-conversion strategy provides a new approach to high-performance mechanical light energy-conversion systems and may further inspire more diverse functional applications of classical PML materials.
