“…The determined E a value for thermal quenching is 0.2206 eV, which is further supported by recent literature, i.e. , Ca 2 LuHf 2 Al 3 O 12 :Ce 3+ , Tb 3+ , 53 Ca 2 YHf 2 Al 3 O 12 :Ce 3+ ,Tb 3+ , 54 Ca 14 Al 10 Zn 6 O 35 :Tb 3+ , 55 Ba 3 YB 3 O 9 :Tb 3+ , 56 RbBaBP 2 O 8 :Tb 3+ , 57 Ca 2 Ga 2 SiO 7 :Tb 3+ , 58 La 4 GeO 8 :Tb 3+ , Eu 3+ , 59 Ba 3 (ZnB 5 O 10 )PO 4 :Tb 3+ , 60 Bi 3 TeBO 9 :Tb 3+ 61 and Na 5 Lu 9 F 32 :Tb 3+ . 62 In the present study, multiphonon-assisted nonradiative transition did not occur.…”

“…The 5 D 4 / 7 F j (j = 0-6) transitions are oen the source of the distinctive green emission of Tb 3+ ions, while the concurrently existing 5 D 3 / 7 F j transitions that produce blue or ultraviolet light are also conceivable. 23,24 Moreover, the luminescence of 4felectrons is mainly a characteristic inherent to the RE ions and remains unaffected by the crystal eld surrounding the luminescent center. This is because the 4f-electrons within the inner layer of Tb 3+ are protected by the outer electrons of 5s 2 5p 6 .…”
