“…There are several mixed scintillators among them: BaBrI:Eu with the light yield of up to 112000 photlMeV, BaBrCI:Eu with light yield of 52000 phot/MeV, BaC1T:Eu with light yield of 54000 phot/MeV, BaFI:Eu with light yield of 55000 phot/MeV [1]. Improvement of light yield was achieved in oxide scintillators as well, for, example, light yield of up to 46000 phot/MeV was reported for crystals of (Y,Lu,GdMAlyGal_x)sOI2 family [2,3], and light yield of 34000 phot/MeV was demonstrated with LU2xGdz_2xSiOs:Ce (LGSO:Ce) [4].…”
