Scintillation properties of Ce-doped Tb3Al5O12

Inorganic scintillating materials and scintillation detectors

“…108) We have continued to study Ce-doped garnet materials, and very recently, we discovered that Ce-doped Tb 3 Al 5 O 12 (TAG) also shows very promising scintillation properties: a high light yield of 57,000 ph/MeV with a decay time of 38 ns. 109,110) Before this study, Ce-doped TAG was only considered in a thin-film form, 111) and it was impossible to evaluate the scintillation light yield under γ-ray irradiation. Therefore, this discovery opens a new possibility to be considered as a host of garnet scintillators.…”

The resulting spectrum has one broad absorption peak centered around 900 nm and a number of broad and overlapping absorption peaks starting at 1.…”

“…In recent years, tremendous efforts have been dedicated to the search for and development of a significant number of Tb-based new crystals, essentially because of their potentially remarkable optical, magnetic and magneto-optic properties for the prospects of Faraday rotator [1][2][3][4][5], solid state lasers [6], phosphors [7][8], and biological cell imaging [9]. Tb 3+ ions have been proved interesting for the Faraday rotation property which they induce in the visible and near infrared spectral range in such crystals as Tb5Ga3O12 (TGG), or in Tb2O3 crystals recently grown for the first time [1].…”

Scintillation and Dosimetric Properties of Monocrystalline and Polycrystalline Li2B4O7

“…(7)(8)(9)(10)(11) These scintillators are used for medical imaging, (4) nondestructive inspection, (12) and well logging. (13,14) Although many types of scintillator have been reported, it is still attractive to develop novel scintillators with higher light yields (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) and shorter decay times. (27,28) In the radiation dosimetry technique, personal dosimeters are made of dosimetric materials that are mainly solid-state storage phosphors.…”
