Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Harnessing Self‐Sensitized Scintillation by Supramolecular Engineering of CsPbBr3 Nanocrystals in Dense Mesoporous Template Nanospheres

Advanced Materials, EarlyView.
Perovskite CsPbBr3 nanocrystals exhibit bright emission, fast response, and solution processability, but their nanoscale size limits efficient radiation detection. Organizing them into porous SiO2 mesospheres enhances radioluminescence up to 40 times, achieving an optimal combination of light yield, fast scintillation, and processability, providing a ...
