“…To investigate further about ionizing radiation induced luminescence, in this time, I evaluated scintillation, OSL, and TSL properties of Eu-doped (1, 2, 3, and 4%) LiCaAlF 6 [7,8], Ce-doped (2, 3, and 4%) LiCaAlF 6 [9,10], and Pr-doped (0.25, 0.3, 0.4, 0.6, 0.8, and 1%) LuAG [11,12] on a comparison with previously studied Ce-doped CaF 2 [6]. LiCaAlF 6 crystals were fabricated by Tokuyama Corp. and these materials became commercially available products.…”

a b s t r a c tIn 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 CaF 2 , Eu-doped LiCaAlF 6 , Ce-doped LiCaAlF 6 , and Pr-doped LuAG were evaluated on their scintillation, OSL, and TSL properties. In Ce-doped CaF 2 , Eu-doped LiCaAlF 6 , and Pr-doped LuAG, scintillation and dosimeter properties showed a complementally relation while Ce-doped LiCaAlF 6 exhibited different properties.

“…In the case of Pr-doped Lu 3 Al 5 O 12 , it has a light yield of 20,000 ph/MeV and the energy resolution of 3–4% at 662 keV. 22) The energy resolutions of Ce-doped LaBr 3 23) which has a light yield of 60,000 ph/MeV and Eu-doped SrI 2 , 19) which shows 80,000 ph/MeV, are also 3–4% at 662 keV. Therefore, if the scintillation light yield is sufficiently high, the energy resolution is no longer governed by Poisson statistics.…”

Scintillation materials and detectors that are used in many applications, such as medical imaging, security, oil-logging, high energy physics and non-destructive inspection, are reviewed. The fundamental physics understood today is explained, and common scintillators and scintillation detectors are introduced. The properties explained here are light yield, energy non-proportionality, emission wavelength, energy resolution, decay time, effective atomic number and timing resolution. For further understanding, the emission mechanisms of scintillator materials are also introduced. Furthermore, unresolved problems in scintillation phenomenon are considered, and my recent interpretations are discussed. These topics include positive hysteresis, the co-doping of non-luminescent ions, the introduction of an aimed impurity phase, the excitation density effect and the complementary relationship between scintillators and storage phosphors.
