High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass

open access: yesRare Metals, EarlyView.
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...
