Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

open access: yesAdvanced Optical Materials, EarlyView.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

CT-Dose Measurement of the Spinal Cord Region Using XR-QA2 Radiochromic Films and TLD 100H Dosimeters

open access: yesInstruments, 2020
The European Directive 2013/59/Euratom focuses on the radiation protection and patient dosimetry. In particular, the dose absorbed by serial organs such as the spinal cord due to diagnostic exams plays a crucial role in the appraisal of medical exposure.

High‐Security X‐Ray Imaging Encryption Based on Irreversible Acid‐Responsive Radioluminescence Memory Scintillator

open access: yesAdvanced Science, EarlyView.
An irreversible acid‐responsive radioluminescence memory scintillator, Zn1.3Ga1.4Ge0.3O4:Cr3+@Zn2GeO4:Eu3+ (ZGGO@ZGO), is developed in this work. The engineered dual‐layer security system composed of ZGGO@ZGO and ZGO achieves a combined effect of visual misdirection and sequential logic gates requiring acid treatment and CCD detection, significantly ...

Bimodal Mechanoluminescence Enables Multicolor Luminescent Tailing for Ultra‐Accurate Loading Speed Visualization and Detection

open access: yesAdvanced Science, EarlyView.
MgF2 exhibits a speed‐dependent mechanoluminescence (ML) color distribution arising from distinct ML lifetimes, showing blue emission under slow sliding and multicolor emission under fast sliding. A promising method for evaluating ML lifetime is proposed based on the trailing effect. By synergistically integrating instantaneous and persistent ML with a
