The sensitive detection of X‐rays embodies an important research area, being motivated by a common desire to minimize the radiation doses required for detection. In article number 1804550 , Julian A. Steele, Maarten B. J. Roeffaers, and co‐workers detail the photophysical properties contributing to the impressive performance of highly sensitive X‐ray detectors based on double perovskite Cs 2 AgBiBr 6 . Upon cooling the device, enormous performance enhancements are realized and are tracked via optical‐based studies, closing the gap between the interpretation of high‐ and low‐energy photogenerated charges.
