Ionizing radiation induced emission: Scintillation and storage-type luminescence

In solid state ionizing radiation detectors, mainly two types of luminescent materials, scintillators and dosimeter materials, have been investigated for a long time. The former one transduces the energy of high energy ionizing radiation (keV-GeV) to thousands of UV-visible photons immediately and the latter storages energies under radiation exposure. After the excitation by visible photons (OSL) or thermal energies (TSL), dosimeter materials release the storage energies by UV-visible emission. In this work, Ce-doped CaF2, Eu-doped LiCaAlF6, Ce-doped LiCaAlF6, and Pr-doped LuAG were evaluated on their scintillation, OSL, and TSL properties. In Ce-doped CaF2, Eu-doped LiCaAlF6, and Pr-doped LuAG, scintillation and dosimeter properties showed a complementally relation while Ce-doped LiCaAlF6 exhibited different properties.
