On July 10, 2026, Professor Omar F. Mohammed from King Abdullah University of Science and Technology delivered an academic lecture entitled “Glassy X-ray Imaging Scintillators: From Laboratory Discovery to Market Translation” at the Department of Chemistry, Tsinghua University.
Professor Mohammed is a Professor at KAUST. His research focuses on advanced optoelectronic materials and devices, including solar cells, light-emitting diodes, and X-ray imaging scintillators, supported by ultrafast laser spectroscopy, 4D electron imaging, and computational materials science.
In his lecture, Professor Mohammed introduced recent advances in glassy scintillator materials for X-ray imaging. Conventional crystalline scintillators have long dominated the field owing to their high efficiency. However, their high-temperature fabrication, limited formability, challenges in large-area processing, and relatively high cost have restricted their broader application in next-generation imaging screens.To address these limitations, Professor Mohammed presented a new class of high-performance copper iodide cluster glass scintillators, including mixed-metal Mn–Cu halide glasses. He discussed their scalable fabrication strategies, optical and imaging performance, and the potential advantages of glassy materials in large-area device preparation. The lecture also highlighted ongoing efforts to scale up fabrication and promote industry collaboration, aiming to benchmark material performance and advance these scintillators toward commercial validation.
