Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Promoted Current Injection in GaInN/GaN Multi‐Quantum Nanowire‐Based LEDs Coated With AZO Using Atomic Layer Deposition

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Conformal Al‐doped ZnO (AZO) electrodes deposited by atomic layer deposition (ALD) overcome current‐injection limitations in coaxial GaInN/GaN nanowire LEDs. Uniform electrode coverage across nanowire sidewalls and bottom regions promotes efficient carrier injection and radiative recombination across multiple crystal facets, enhancing emission ...

Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while
