CsPbBr3–Nanodiamonds Hybrid Wafers for Mechanically Robust, High‐Performance X‐Ray Detection

Advanced Electronic Materials, Volume 12, Issue 10, 25 May 2026.
NDs‐engineered CsPbBr3 hybrid wafers, fabricated via scalable solid‐state grinding and cold pressing, utilize trace NDs to regulate mechanochemical conversion, promote heterogeneous nucleation, bridge grain boundaries, and passivate interfacial defects. The optimized wafer exhibits dense microstructures, improved charge transport, reduced dark current,

Halide perovskites in wide‐spectrum photodetection

Bulletin of the Korean Chemical Society, Volume 47, Issue 5, Page 504-526, May 2026.
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.

Performance of multielement CdZnTe detectors [PDF]

SPIE Proceedings, 1999
Single-element CdZnTe detectors are limited in size, and therefore efficiency, by the poor hole transport, even with a coplanar grid. We are investigating the possibility of a 27-element array using 15 mm X 15 mm X 15 mm elements for gamma-ray energies to 10 MeV for NASA planetary missions.
