Schottky Barrier Engineering in n‐Type Organic Source‐Gated Transistors Enabling High Conductance

Advanced Materials Technologies, EarlyView.
This study introduces a modified source electrode architecture for n‐type organic source‐gated transistors (OSGTs). By integrating Schottky and Ohmic contact regions, the design achieves a thinner depletion envelope, enhancing mobility nearly tenfold and reducing threshold voltage.

Reverse Intersystem Crossing and Exciton Harvesting: A Pathway to Low Threshold in Multi‐Resonant TADF Electrically Pumped Organic Semiconductor Lasers

Advanced Optical Materials, EarlyView.
Electrically pumped organic lasing thresholds are lowered by mitigating triplet accumulation through a tailored host‐guest system. Integrating the multi‐resonant TADF emitter DABNA‐2 into a triplet‐scavenging BSBCz host suppresses singlet‐triplet annihilation.

Elucidating the Mechanism behind the Enhancement of Persistent Luminescence in ZnGa2O4: Cr3+ Nanoparticles upon H2O2 Exposure

Advanced Optical Materials, EarlyView.
ABSTRACT Persistent luminescence (PersL) materials exhibit prolonged emission of light, lasting from seconds to hours after stopping the excitation. At the nanoscale, they have attracted considerable interest for applications in in vivo imaging, photodynamic therapy, and biosensing.
