Lead‐Free Tin‐Based Perovskite LEDs Toward Rec. 2020: Organic Anion Coordination for Oxidation Suppression

open access: yesAdvanced Science, EarlyView.
This study introduces an organic anion‐coordination for oxidation suppression (OCOS) strategy using alkali metal–organic anions (e.g., KEtO) to stabilize Sn2+ in lead‐free Sn‐based perovskites for PeLEDs. By coordinating with Sn2+ and inhibiting vacancies, OCOS enhances film quality, EQE (to 10.01% at 638 nm), and luminance (to 139.9 cd m−2 ...

In Situ Construction of Cu+‐Ov‐Ce3+ Sites on CeO2 for Efficient NH3 Oxidation

open access: yesAdvanced Science, EarlyView.
An advanced CeCuOx nanorod catalyst is developed via in situ hydrothermal synthesis, and it exhibits remarkable NH3‐SCO activity, N2 selectivity, and stability. The addition of Cu induces the formation of abundant Cu+‐Ov‐Ce3+ active sites on CeO2 and switch the primary intermediate species of NH3 oxidation from bidentate nitrate species to monodentate ...

High‐Performance Micro‐LED Displays via Etching‐Damage‐Free Pixelation Strategy for Multifunctional Integrated Applications

open access: yesAdvanced Science, EarlyView.
A novel etching‐damage‐free pixelation approach based on F ion implantation has been developed for the fabrication of micro/nano‐LED arrays with a pixel density reaching 25,400 ppi. This method offers the advantages of high resolution, high efficiency, and high brightness, making it highly suitable for applications in near‐eye displays, optical ...
