Luminescent and scintillation properties of the Ce3+ doped Y3−Lu Al5O12:Ce single crystalline films

Growth and luminescent properties of scintillators based on the single crystalline films of Lu3−xGdxAl5O12:Ce garnet

“…2a) and change of the respective DE¼E 2 -E 1 values(Fig. 2c), we found about 17% decrease of the crystal field strength in Lu 0.5 Gd 2.5 Al 5 O 12 :Ce garnet in comparison with Lu 3 Al 5 O 12 :Ce counterpart[4,17].…”

“…The Pb 2+ ions are very effective quencher of the Ce 3 + luminescence in garnet SCF scintillators [3,4,16]. In our opinion, such increasing the Pb 2+ contamination in Gd rich SCF is stimulated by the increase of lattice constant of respective garnets (Fig.…”

“…4b) (see also [4,21,22]). The Gd 3+ doping is also accompanied by significantly decreasing the intensity of the X-ray excited luminescence of Lu 3Àx Gd x Al 5 O 12 :Ce SCFs (Fig.…”

“…The bands at the 260-265 nm range are caused by Pb 2+ flux related impurity and correspond to the 1 S 0 ! 3 P 1 transitions [3,4,16].…”

“…For this purpose the SCF of Y 3 Al 5 O 12 :Ce (YAG:Ce), Lu 3 Al 5 O 12 :Ce (LuAG:Ce), Gd 3 Ga 5 O 12 :Tb (GGG:Tb) and GGG:Eu garnets [3][4][5], LSO:Tb and LYSO:Ce,Tb orthosilicates [6,7] and LuAP:Ce,Tb perovskites [7,8] were successfully developed using the Liquid Phase Epitaxy (LPE) method in the last decade.…”
