Optimizing Perovskite Surfaces to Enhance Post‐Treatment for Efficient Blue Mixed‐Halide Perovskite Light‐emitting Diodes

open access: yesAdvanced Materials, EarlyView.
The halide postdeposition process is optimized by engineering blue mixed‐halide 3D perovskites with acetate‐rich surfaces. This engineered perovskite minimizes the washing effect of isopropanol, which slows down surface reconstruction and ultimately promotes the formation of a uniform mixed‐halide perovskite phase.

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

open access: yesAdvanced 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%.

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.
