Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

open access: yesAdvanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

open access: yesAdvanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Unveiling How Electric Fields Influence Electroluminescent Properties in Light‐Emitting Electrochemical Cells via Operando Optically Detected Magnetic Resonance

open access: yesAdvanced Optical Materials, EarlyView.
Electroluminescence‐detected magnetic resonance (ELDMR) is used to probe electron–hole pairs in light‐emitting electrochemical cells under operando conditions. The measurements reveal sweep‐dependent hysteresis linked to changes in the internal electric field, which governs recombination efficiency. These findings demonstrate the capability of ELDMR to
