“…The values of afterglow at 20 ms of the samples were 46% (Cr 0.1%), 55% (Cr 0.5%) and 39% (Cr 1%). Compared with the CdWO 4 , afterglow of Cr:YAP crystals is very long [18]. It is considered to be attributed to long decay time of Cr:YAP (Fig.…”

The Czochralski method is one of the very few melt growth techniques that are industry friendly when considering the combination of quality, dimensions, and cost of the produced crystals suitable for their commercialization in scintillation detectors. This method is one of the oldest and most developed crystal growth processes regarding an adequate understanding the physical phenomena observed during solidication process and its practical expansion especially in the industrial scale production. It allows controllable formation of single-crystalline cylindrical ingots of various inorganic scintillation materials. The review summarizes recent progress on the Czochralski growth of a number of scintillation materials. The oxide crystals are mainly considered including the Ce and Pr--doped RE3Al5O12, RE = Y, Lu, aluminum garnets and newly discovered ultraecient Ce-doped Gd3(Ga,Al)5O12 multicomponent garnet, high density PbWO4 and CdWO4 tungstates, Ce-doped RE2SiO5, RE = Y, Gd, Lu, oxyorthosilicates and (Y,Lu)AlO3 aluminum perovskites and nally the classical Bi4Ge3O12 scintillator. Additionally, the details of the growth of other practically important non-oxide crystals, namely the Ce and Eu-doped LiCaAlF6 neutron and ultraecient Ce-doped LaBr3 scintillators, are discussed. The potential of novel micro-pulling down growth method is briey described in the combinatorial search for new scintillator materials. Selected luminescence and scintillation characteristics including the spectra and decay kinetics, light yield and radiation resistance are also illustrated and overviewed.

“…It is known that molybdates and tungstates are a very important family of inorganic materials that have a high potential application in various fields, such as photoluminescence, microwave applications, optical fibers, scintillator and laser materials [1][2][3][4][5][6][7][8][9][10][11][12]. As phosphors, molybdates and tungstates have some advantages, e.g.…”
