Perovskite Light‐Emitting Diodes with Quantum Wires and Nanorods

open access: yesAdvanced Materials, EarlyView.
This review focuses on low‐dimensional perovskite materials and discusses their applications in light‐emitting diodes (LEDs). Special attention is given to the introduction of perovskite quantum wires and nanorods, two unique types of one‐dimensional (1D) materials, and their interesting optoelectronic properties.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

open access: yesAdvanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

The Deepest Blue: Major Advances and Challenges in Deep Blue Emitting Quasi‐2D and Nanocrystalline Perovskite LEDs

open access: yesAdvanced Materials, EarlyView.
In this review, the recent development of deep‐blue (≤465 nm) perovskite light‐emitting diodes (PeLEDs) are summarized, using different perovskite nanomaterials, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi‐2D thin film, 3D bulk thin film, as well as lead‐free perovskite nanomaterials.
