Needs, trends, and advances in scintillators for radiographic imaging and tomography
/ Wang, Zhehui (Los Alamos) ; Dujardin, Christophe (ILM, Lyon) ; Freeman, Matthew S. (Los Alamos) ; Gehring, Amanda E. (Los Alamos) ; Hunter, James F. (Los Alamos) ; Lecoq, Paul (CERN) ; Liu, Wei (Mayo Clinic) ; Melcher, Charles L. (U. Tennessee, Knoxville) ; Morris, C.L. (Los Alamos) ; Nikl, Martin (Prague, Inst. Phys.) et al.
Scintillators are important materials for radiographic imaging and tomography (RadIT), when ionizing radiations are used to reveal internal structures of materials. Since its invention by Röntgen, RadIT now come in many modalities such as absorption-based X-ray radiography, phase contrast X-ray imaging, coherent X-ray diffractive imaging, high-energy X- and $\gamma-$ray radiography at above 1 MeV, X-ray computed tomography (CT), proton imaging and tomography (IT), neutron IT, positron emission tomography (PET), high-energy electron radiography, muon tomography, etc. [...]

The crystals of (Lu,Gd)3(Ga,Al)5O12 multicomponent garnets with high density ρ and effective atomic number Zeff are characterized by high scintillation efficiency and a light yield value up to 50,000 ph/MeV. During recent years, single-crystalline films and composite film/crystal scintillators were developed on the basis of these multicomponent garnets. [...]

Compositional engineering of multicomponent garnet scintillators: towards an ultra-accelerated scintillation response
/ Martinazzoli, Loris (CERN ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Nargelas, Saulius (Vilnius, Inst. Theor. Phys. Astron.) ; Boháček, Pavel (Prague, Inst. Phys.) ; Calá, Roberto (CERN ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Dušek, Michal (Prague, Inst. Phys.) ; Rohlíček, Jan (Prague, Inst. Phys.) ; Tamulaitis, Gintautas (Vilnius, Inst. Theor. Phys. Astron.) ; Auffray, Etiennette (CERN) ; Nikl, Martin (Prague, Inst. Phys.)
Optical, luminescence and scintillation characteristics were studied in garnet-type GAGG single-crystal scintillators grown by the Czochralski method and heavily doped with a cerium activator and a magnesium codopant at different concentrations. Emission quenching due to the formation of closely spaced Ce–Mg pairs accelerating the photoluminescence and scintillation decays down to a few nanoseconds and substantial suppression of slower decay components are observed.

Core–shell ZnO:Ga-SiO$_2$ nanocrystals: limiting particle agglomeration and increasing luminescence via surface defect passivation
/ Procházková, Lenka (Prague, Tech. U. ; Prague, Inst. Phys.) ; Vaněček, Vojtěch (CTU, Prague) ; Čuba, Václav (CTU, Prague) ; Pjatkan, Radek (Unlisted, CZ) ; Martinez-Turtos, Rosana (Milan Bicocca U.) ; Jakubec, Ivo (ASCR, Prague) ; Buryi, Maksym (Prague, Inst. Phys.) ; Omelkov, Sergey (Tartu U.) ; Auffray, Etiennette (CERN) ; Lecoq, Paul (CERN) et al.
Heat treatment is needed to increase the luminescence intensity of ZnO:Ga particles, but it comes at the cost of higher particle agglomeration. Higher agglomeration results in low transparency of scintillating powder when embedded in a matrix and constitutes one of the biggest disadvantages, besides low light yield and low stopping power, of ZnO:Ga powder.

Recent developments in medical imaging techniques, in particular, those in time-of-flight positron emission tomography put new challenges on scintillating material performance that cannot be fulfilled by conventional scintillators. Bright and ultrafast nanoparticles represent promising candidates to build up an advanced detection system needed. [...]
