Dibenzophenazine‐Fused Heterocyclic Luminophores: Decoding High‐Performance Organic Light‐Emitting Diodes Based on Long‐Wavelength Exciplex

ABSTRACT Developing highly efficient long‐wavelength exciplexes remains a challenge due to the constraints of the energy gap law and severe non‐radiative loss. In this study, we report a rigid nitrogen‐rich donor, 3N, featuring the first fused framework constructed from two anti‐...

Highly Efficient Non‐Doped Blue Electro‐Fluorescence With Fast Carrier Mobilities: Hybrid Local and Charge‐Transfer (HLCT) Excited State and Regularly Stacked Aggregate

ABSTRACT Non‐doped organic light‐emitting diodes (OLEDs) offer simpler fabrication and lower manufacturing costs than traditional doped OLEDs, attracting increasing attention in both scientific research and industrial applications. However, aggregation‐caused quenching (ACQ) and...

Trace Doping for Changing the Crystallization of Photonic Glass

ABSTRACT Crystallization in glasses is a universal phenomenon and nucleating agents are often employed as they are essential for controlling this crystallization process. It is widely recognized that nucleating agents, such as TiO 2 and ZrO 2 , function by forming heterogeneous i...

Architecting Anisotropic Force‐Responsive Bidirectional High‐Contrast Three‐Color Fluorescence Switches via Effective Molecular Modulation for High‐Security Information Storage

ABSTRACT Although bidirectional three‐color fluorescent molecular switches triggered by anisotropic force are promising for enhancing the security of information storage, the engineering and development of such force‐responsive smart emissive materials face significant challenges...

Suppressing Photothermal Artifacts in Flexible Fluorescent Fiber‐Optic Sensors for Accurate and Precise In Situ Temperature Monitoring

ABSTRACT Ratiometric flexible fluorescent fiber‐optic sensors, featuring self‐calibration and precise spatial localization, are emerging as a robust platform for in situ thermal monitoring, advancing applications such as battery safety management and biomedical diagnostics. Howev...

All-dielectric grating quasi-BIC for upconversion luminescence enhancement and cryogenic temperature sensing

Upconversion nanoparticles (UCNPs) are limited in their applications in non-contact temperature measurement and biomedicine due to their low luminescence quantum efficiency. Traditional surface plasmon resonance (SPR) structures are restricted in their performance and practical a...
