Gd-admixed (Lu,Gd)AlO single crystals: breakthrough in heavy perovskite scintillators

Nature.com
 2021-10-22

Cover picture for the articleWe report a breakthrough concept for a bulk single crystal as a heavy aluminum perovskite scintillator, where due to bandgap engineering by a balanced Gd admixture in a Lu cation sublattice, the scintillation performance dramatically increases. In an optimized composition of (Lu, Gd)AlO3:Ce (LuGdAP:Ce), the light yield approaches 21,000 phot/MeV, which...
