A research team has developed a new type of glass screen designed to improve X-ray imaging performance while operating at lower radiation doses. Published in ACS Energy Letters, the study details how an innovative scintillator screen can produce high-resolution images while requiring less X-ray exposure. The technology could expand capabilities for non-destructive testing and analytical imaging applications.
A scintillator is a specialized screen that captures X-rays passing through an object and converts them into flashes of visible light. According to the corresponding author, Osman Bakr, PhD, "The more efficient the scintillator is at this conversion, the clearer the final digital image becomes and the lower the dose of radiation required to create it." Traditional scintillators rely on rigid crystals, which can limit imaging applications involving non-planar surfaces or environments with high attenuation.
Overcoming the resolution limits of X-ray characterization
To enhance the performance of glass-based scintillators, Bakr, along with Mehmet Bayindir, PhD, and colleagues, incorporated nanoclusters composed of copper, iodine, and an organic ligand into a glass matrix. By designing the material from the bottom up, the team created a quantum glass that combines characteristics of both molecular systems and nanocrystals.
In laboratory evaluations, the new screen successfully captured detailed X-ray images of a memory card and an insect, revealing intricate structural features and achieving sub-three-micrometer resolution. Because the glass efficiently converts X-rays into visible light, the system was able to generate high-resolution images while operating at lower X-ray doses.
Water often presents challenges for X-ray imaging because it can scatter signals and reduce image quality. The new scintillator addressed this issue by capturing clear scans of a fish tail underwater with image quality comparable to scans acquired in air.
Another notable characteristic of the nanocluster glass is its thermal response. When heated to 107 degrees Fahrenheit (42 degrees Celsius), the material becomes flexible and rubbery. This allows researchers to mold the screen into curved shapes, a capability not possible with conventional rigid crystal scintillators. According to first author Bashir Hasanov, "this allows the screen to be as moldable as plastic while maintaining the high-performance imaging capabilities of a rigid crystal, opening a new frontier for three-dimensional X-ray diagnostics using curved surfaces."
Potential implications for analytical imaging workflows
For lab managers overseeing materials analysis, metallurgy, or characterization facilities, the study highlights how advances in scintillator design could expand imaging capabilities. The quantum glass combines high X-ray-to-light conversion efficiency with unusual mechanical flexibility, allowing it to be molded into curved shapes while maintaining imaging performance.
This capability could enable future detector systems that better accommodate complex sample geometries and challenging imaging environments, including underwater applications. Although additional development will be required before widespread adoption, the material demonstrates how next-generation scintillators may improve image quality while operating at lower X-ray doses.
