Abstract Persistent luminescence (PersL) in inorganic phosphors offers great potential for anti‐counterfeiting and optical storage, with optimization of PersL, multicolor tuning, defect engineering. This study presents a Ca 3 Ga 2 Ge O 12: Pr 3+ (CGGO:Pr) phosphor long‐lasting PersL emissions. Aliovalent codoping Er Yb ions optimizes deep/shallow trap redistribution, controlling depths from 0.98 to optimal 0.73 eV through the creation new shallow electron traps (Yb • , ) alongside existing V levels. The smart /Er /Yb :CGGO exhibits three‐dimensional visible emissions under 275 380 nm excitation, as well upconversion 980 laser irradiation. Hybrid density functional calculations, thermoluminescence, positron annihilation lifetime spectroscopy revealed nature different PersL. Together, single system featuring has been developed, exhibiting improved regulated (≈0.73 eV) suitable robust multimodal documents, pharmaceuticals, industrial products. Furthermore, composite PMMA‐CGGO:Pr films have shown remarkable capability X‐ray imaging, achieving resolution 4 lp/mm, which exceeds that commercial Gd S:Tb screens. These findings highlight this work advanced imaging applications, offering enhanced controlled depths.

Abstract Lanthanide (Ln 3+ )‐doped upconversion nanocrystals (NCs) have attracted great attention due to their outstanding luminescent performance and wide applications in various fields. However, the preparation of most Ln ‐doped NCs requires rigorous conditions such as high reaction temperature, long time, strict anhydrous oxygen‐free environment, tedious post‐treatment process. Herein, sub‐100 nm Yb /Er codoped K 3 ZrF 7 octahedral are prepared by an extremely simple coprecipitation method (10 s only at room temperature). The resulting show excellent luminescence (UCL), significantly superior both conventional high‐temperature‐synthesized counterparts room‐temperature‐synthesized NaBiF 4 :Yb/Er controls. More importantly, abnormal thermally enhanced UCL over a temperature range from 473 is found these NCs, making them promising candidates for ratiometric thermometry applications. By employing intensity ratio between two non‐thermally coupled energy levels Er , namely F 9/2 2 H 11/2 display extraordinarily absolute sensitivity 443.2% −1 comparatively large relative 1.55% temperature. These results reveal that can not be facilely via ultrafast room‐temperature synthesis, but also hold potential areas optical sensing biological
