Luminescence and scintillation characteristics of Gd3Al2Ga3O12:Ce3+ scintillators

Nonlinear behavior of structural and luminescent properties in Gd(NbxTa1-x)O4 mixed crystals

“…5a). The similar effect of light output enhancement has been previously observed in some mixed oxide crystals at room temperature [9][10][11][12][13][14][15][16]. Here we demonstrate that the effect can be also observed at low temperatures as well.…”

“…Engineering of mixed compositions by Nb 5+ /Ta 5+ substitution can be a tool to enhance the light yield and other scintillation parameters by analogy with many other mixed systems studied recently [9][10][11][12][13][14][15][16]. It was shown that the tendency to light yield increase in mixed crystals is linked to the spatial distribution of substituted atoms in solid solutions which, in turn, determines their electronic properties.…”

Photoluminescence studies on energy transfer processes in cerium-doped Gd3Al2Ga3O12 crystals

“…This value is almost same as the lifetimes of the Ce 3+ emission reported in Refs. [8,17]. The background corresponds to the pile-up component of the Ce 3+ emission [18].…”

Light‐yield improvement trends in mixed scintillation crystals

“…Improvement of light yield was achieved in oxide scintillators as well. For example, light yield of up to 56 000 ph MeV −1 was reported for crystals of (Y,Lu,Gd) 3 (Al y Ga 1– x ) 5 O 12 garnet family and light output of 34 000 phot MeV −1 was demonstrated for Lu 2 x Gd 2–2 x SiO 5 :Ce (LGSO:Ce) silicates . However, the rate of light‐yield improvement in mixed crystals has not been systematically studied before.…”
