Scientists from the National University of Singapore (NUS) have developed a highly effective and general molecular design that enables an enhancement in radioluminescence within organometallic scintillators by more than three orders of magnitude. This enhancement harnesses X-ray-induced triplet exciton recycling within lanthanide metal complexes.
Detection of ionizing radiation is crucial in diverse fields, such as medical radiography, environmental monitoring and astronomy. As a result, significant efforts have been dedicated to the development of luminescent materials that respond to X-rays.
However, current high-performance scintillators are almost exclusively limited to ceramic and perovskite materials, which face issues such as complex manufacturing processes, environmental toxicity, self-absorption and stability problems.
