Researchers at the Argonne National Laboratory (ANL) have developed nanoscale quantum shells that can be used alongside powerful X-ray sources like the Advanced Photon Source (APS) for ultrafast detection of high-energy particles and producing high-quality images.
Researchers at the Argonne National Laboratory have developed nanoscale quantum shells that work as advanced electron and X-ray scintillators. This innovation can lead to exciting developments in particle physics, medical imaging, and X-ray-based defense technologies.
“An everyday application for scintillator technology can be found in a dentist’s office, where X-ray beams are shone through a patient’s mouth and onto a film of a reactive material that imprints an image of the teeth for the dentist to check for potential defects,” the researchersScintillators hold great importance in medical imaging and various other applications that utilize high-energy particles.
A shorter glow time enables quicker, and more detailed imaging. “The quantum shell scintillator achieves a single-digit nanosecond lifetime while preserving efficiency levels equal to traditional scintillators,” Benjamin Diroll, one of the researchers, said. Additionally, traditional scintillators are millimeters thick, causing light to release from multiple areas and resulting in blurred images.“We realized that we could make quantum shell scintillators much thinner, just a couple of micrometers while achieving both strong X-ray absorption and high spatial resolution imaging,” Burak Guzelturk, lead researcher and a physicist at ANL, said.The application of quantum shells isn’t limited to dental X-rays and other types of medical diagnostics.
