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

Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Cation‐Engineered Post‐Treatment for Blue Perovskite Light‐Emitting Diodes
This work presents a cation‐engineered post‐treatment strategy for high‐performance mixed‐halide blue PeLEDs. By investigating the role of 4‐fluorophenylethylammonium (FPEA+) versus conventional phenylethylammonium (PEA+) organic cations in post‐treatment agents, it demonstrates that FPEA+ enables superior preservation of the 3D perovskite structure ...

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.

Determining the Width of the Dynamic Emission Zone in Light‐Emitting Electrochemical Cells
The width of the dynamically evolving emission zone (EZ) in light‐emitting electrochemical cells (LECs) is important since it has a strong influence on the emission efficiency. Here, a spectral simulation and measurement method is presented, which is utilized for the determination of the EZ width evolution during the initial operation of a common ...

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...
