| description | Abstract Long‐persistent luminescent (LPL) materials have attracted considerable research interest due to their extensive applications and outstanding afterglow performance. However, the performance of red LPL materials lags behind that of green and blue materials. Therefore, it is crucial to explore novel red LPL materials. This study introduces a straightforward and viable strategy for organic–inorganic hybrids, wherein the organic ligand 1,3,6,8‐Tetrakis(4‐carboxyphenyl)pyrene (TCPP) is coordinated to the surface of a red persistent phosphor Sr0.75Ca0.25S:Eu2+ (R) through a one‐step method. TCPP serves as an antenna, facilitating the transfer of absorbed light energy to R via triplet energy transfer (TET). Notably, the initial afterglow intensity and luminance of R increase by twofold and onefold, respectively, and the afterglow duration extends from 9 to 17 min. Furthermore, this study involves the preparation of a highly flexible film by mixing R@TCPP with high‐density polyethylene (HDPE) to create a sound‐controlled afterglow lamp. This innovative approach holds promising application prospects in flexible large‐area luminescence, flexible wearables, and low‐vision lighting. |
