Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

Advanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

Advanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Enhancing Amplified Spontaneous Emission in Perovskite Thin Films by Thickness Regulation: Insights into Carrier Distribution and Optical Confinement

Advanced Optical Materials, EarlyView.
This study reveals the critical influence of film thickness and excitation wavelength on the ASE threshold in metal halide perovskites. By optimizing these factors, the ASE threshold is significantly reduced, providing key insights into optical confinement and carrier distribution for advancing electrically pumped perovskite lasers.

From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance

Advanced Optical Materials, EarlyView.
Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings
