Abstract In recent years, organic room temperature phosphorescence (RTP) materials have been well developed. Especially, when the compounds are doped into a rigid polymeric matrix, their RTP performances can be greatly enhanced. However, dispersibility and stability of difficult to controlled. Herein, an amorphous homo‐polymer ( P1 ) containing naphthalimide units is synthesized further dispersed polyvinyl alcohol (PVA) matrix via solution mixing procedure. The resultant composites P1@PVA exhibit yellow afterglow under temperature. , chromophores constrained in aggregation state. Unlike crystalline state, intermolecular interactions between aggregated enhanced, while π–π interaction weakened. presence PVA, non‐radiative decay synergistically suppressed by external hydrogen bonds internal interactions. As results, much Comparing with PVA compounds, lifetime prolonged as 1.5 folds.

Abstract Rare‐earth afterglow materials, with their unique light‐storage properties, show great promise for diverse applications. However, broader applicability is constrained by challenges such as poor solvent compatibility, limited luminescent efficiency, and monochromatic emissions. In this study, these limitations are addressed blending ZnS various rare‐earth phosphors including (Sr 0.75 Ca 0.25 )S:Eu 2+ ; SrAl 2 O 4 :Eu , Dy 3+ Sr MgSi 7 to modulate deep trap mechanisms significantly enhance both the light capture capabilities. Using electrospinning, a large‐area (0.4 m × 3 m) film successfully fabricated tunable colors an extended duration exceeding 30 h. This demonstrates thermoluminescence, enabling potential integration into fire‐rescue protective clothing enhanced emergency visibility. greenhouse settings, it effectively supports chlorophyll synthesis optimizes conditions plant growth over 24‐h cycle. For tunnel garage applications, captures stores from vehicle headlights at distances of up 70 meters. The scalability cost‐effectiveness underscore its considerable real‐world applications across multiple fields, marking significant advancement in sustainable illumination technology.
