White electroluminescence from C- and Si-rich thin silicon oxides

, 2006
International audienceWhite electroluminescence from carbon- and silicon-rich silicon oxide layers is reported. The films were fabricated by Si and C ion implantation at low energy in 40nm thick SiO2, followed by annealing at 1100°C.

Low‐Threshold Red Lasing in Diketopyrrolopyrrole‐Based Organic Semiconductor Films

Angewandte Chemie International Edition, EarlyView.
Low‐threshold organic semiconductor lasers (OSLs) in the red region are achieved using diketopyrrolopyrrole (DPP) derivatives (DPA‐DPPMe and HMAT‐d‐DPP). Molecular design enables precise control of radiative‐decay and molecular orientation, suppressing optical losses and enhancing gain.

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...
