The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.

Organic photodetectors (OPDs) based on polymer donor:non‐fullerene‐acceptor (NFA) bulk heterojunction blends offer strong light‐sensing potential, but require methods for optimization. This work demonstrates NFA dilution as an effective strategy to suppress dark current and enable state‐of‐the‐art performance by disrupting NFA crystallinity.

Optical Fiber Meta‐Tips Based on Partial‐Phase Control
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.
