The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

Advanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different

Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

Advanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

PTFE‐Activated Graphene Overcomes Dispersion Challenges for Scalable Solvent‐Free Fabrication of Ultra‐Thick, High‐Performance Cathodes in Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
PTFE nanoparticle–anchored rGO (rGO@PTFE) for scalable solvent‐free fabrication of ultra‐thick, high‐density cathodes, achieving high conductivity (9.55 S cm−1), lithium transference (0.73), and improved wettability, is developed. The resulting cathode delivers 15.2 mAh cm−2 areal and 563 mAh cm−3 volumetric capacities, with full cells exhibiting 637 ...
