Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

Advanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed

Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

Advanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning

18F‐FGln PET/CT Imaging of Glutamine Uptake Has Potential for Predicting Immunotherapy Response in Hepatocellular Carcinoma

Advanced Science, EarlyView.
18F‐FGln PET/CT imaging serves as a marker of Gln uptake in hepatocellular carcinoma. Tumors with high Gln uptake drive Treg‐mediated immunosuppression and immune evasion during antitumor immunotherapy. Conversely, tumors with low Gln uptake maintain sufficient Gln in the TME, suppressing Tregs and enabling cytotoxic T cells to inhibit tumor growth ...

Optical thermometry and fingerprint detection in SrLa1−xEuxLiTeO6 phosphors with abnormal thermal quenching effect

AIP Advances
To overcome the sensitivity limitation of conventional luminescence intensity ratio optical thermometers, we designed an optical thermometer using double-perovskite SrLa1-xEuxLiTeO6 phosphors based on abnormal thermal quenching effect.

Beyond the Debye Temperature: A Unified Microscopic Framework for Designing Thermally Stable Red‐Emitting Phosphors

Advanced Science, EarlyView.
Local symmetry engineering in noncentrosymmetric Na3EuGe3O9 generates enhanced Eu3+ local dipoles, enabling efficient light–matter interactions, high quantum efficiency, and exceptional thermal stability. A unified microscopic framework reveals the cooperative suppression of multiple thermal‐quenching pathways, resulting in robust red emission in high ...

Interface‐Mediated Self‐Rectifying CsCuCl3 Memristors With Tunable Thresholds for Reconfigurable Neuromorphic Computing

Advanced Science, EarlyView.
Interface‐mediated CsCuCl3 memristors achieve self‐rectification and tunable thresholds, enabling selector‐free 8 × 8 arrays with > 105 ON/OFF and > 104 rectification. Supporting dual‐mode neuromorphic computing, negative thresholds preserve low‐light recognition accuracy (91%), while positive thresholds enable sparsity‐aware edge computing.
