1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

open access: yesAdvanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

Efficient Hole Injection From Indium Tin Oxide in Quantum‐Dot Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
The realization of QLEDs‐based displays remains challenging due to the acidic surface from PEDOT:PSS. Here, an analysis is conducted by examining the degradation mechanism of PEDOT:PSS. By replacing PEDOT:PSS with 2BrCzPA, the formation of strong dipoles at the ITO/2BrCzPA SAM interfaces exhibits excellent hole injection abilities.

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...
