CH3O‐PEABr Passivated Quasi‐2D Perovskite BA2Cs4Pb5Br16 Thin Film for Green Light‐Emitting Diodes

open access: yesAdvanced Electronic Materials, EarlyView.
Green quasi‐2D perovskite LEDs based on CH3O‐PEABr modified BA2Cs4Pb5Br16 films achieve a peak EQE of 19.47%. The suppressed defect density enables high‐performance electroluminescence, offering a scalable strategy for efficient and durable electroluminescent devices.

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

open access: yesAdvanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

open access: yesAggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.

Boosting the Antimicrobial Activity of Quaternary Ammonium Photosensitizers by Janus‐Type AIE Luminogens

open access: yesAggregate, EarlyView.
Novel quaternary ammonium AIE luminogens (AIEgens) with symmetric and Janus structures are rationally designed and prepared for bacteria killings. The integration of experimental and theoretical studies discloses that the Janus‐type AIEgen interacts better with bacterial membranes and shows stronger membrane perturbation, demonstrating superior ...

Microwave‐Facilitated Sensitization Route Boosting Efficiency, Thermostability, and Multifunction of Nanophosphors

open access: yesAggregate, EarlyView.
A microwave‐facilitated sensitization engineering is proposed to construct new NSYP:Ce,Tb NPs with less oxygen vacancy, suppressing energy loss of Ce sensitizers and transferring more energy to Tb activators. As a result, the Ce sensitization for Tb achieves ultrahigh ET efficiency (92.6%), contributing to high IQE of 82.2%, along with outstanding ...
