1.4% External Quantum Efficiency 988 nm Light Emitting Diode Based on Tin‐Lead Halide Perovskite

Advanced Materials, EarlyView.
The tin‐lead based halide perovskite film with the 3‐AMP passivate exhibits a significantly longer carrier lifetime of over 1 µs compared to the neat films (0.43 µs). The optimized tin‐lead halide perovskite LEDs show a single emission peak at 988 nm and an external quantum efficiency (EQE) of ≈1.4%.

Acid/Base‐Responsive Circularly Polarized Luminescence Emitters with Configurationally Stable Nitrogen Stereogenic Centers

Advanced Materials, EarlyView.
Circularly Polarized Luminescence (CPL) emitters based on Tröger's base analogues bearing two peripheral fluorophores (anthracene, pyrene or 9,9‐dimethylfluorene) are prepared following a straightforward and versatile synthetic approach from common precursors.

Efficient White Electroluminescence from Cu‐based Perovskite Achieved by High Hole Injection Core/Shell Structures

Advanced Materials, EarlyView.
This study demonstrates a p‐type cuprous sulfide lattice connectedly capping over Cs3Cu2I5 to form lattice‐matched core/shell nanocrystals by controlling the reactivity of sulfur precursor in the synthesis. The resulting pure white PeLEDs achieved by combining with yellow emission CsCu2I3 exhibit a recorded EQE of 3.45% and a high CRI of 91.

Scaling Up Purcell‐Enhanced Self‐Assembled Nanoplasmonic Perovskite Scintillators into the Bulk Regime

Advanced Materials, EarlyView.
This study presents a scalable approach to enhancing bulk scintillators using nanoplasmonics. By integrating 100‐nm silver nanoparticles with perovskite scintillator nanocrystals in a polymer matrix, significant improvements in light yield and decay rates via the Purcell effect are achieved.
