Donor‐Substituted C(sp3)‐Bridged Phosphorus‐Heterotriangulenes as Blue Thermally Activated Delayed Fluorescence Emitters

Advanced Optical Materials, EarlyView.
The newly developed regioselective strategy for the para‐functionalization of C(sp3)‐bridged phosphorus‐centered heterotriangulene delivers a series of donor‐acceptor emitters exhibiting thermally activated delayed fluorescence. The carbazole‐substituted compounds feature a unique combination of high photoluminescence quantum yields up to 75%, deep ...

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

Advanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.

An Efficient Diamond Raman Amplification Scheme Based on Adaptive Temporal Synchronization

Advanced Photonics Research, EarlyView.
This work reveals an adaptive temporal synchronization effect in delayed diamond Raman amplification, where the Stokes pulse shifts toward the fundamental peak. A periodic amplification scheme based on this phenomenon enables efficient pump recycling and enhanced energy conversion, offering a robust, delay‐tolerant strategy for advanced nonlinear ...

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

Advanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Computational Analysis of a GST‐Based Long‐Wave Infrared Microring Resonator on a ZnSe Platform as a Photonic Sensor

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.
