Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Proximity‐Tuned Magnetic and Transport Anomalies in All‐Epitaxial Fe5−xGeTe2/WSe2 Van der Waals Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...

Electromagnetic Properties of Selected Hexaferrites

open access: yesAdvances in Electrical and Electronic Engineering, 2008
Ba(Sr)(Me12+Me24+)xFe12-xO19 hexagonal ferrites preparation with substitution ratio of 0.0 x 0.6. The iron ionswere substituted by selected cation combinations (divalent Me12+= Ni, Zn, Sn, Co and tetravalent Me24+= Ti, Zr, Ru ions).The samples were synthesised by high energy milling and metallorganic precursor method.
