Spectroscopic properties of Tb3+ ions in YAlO3 crystals

Spectroscopic and magnetic susceptibility analyses of the 7FJ and 5D4 energy levels of Tb3+(4f8) in TbAlO3

“…This set of Stark levels was compared with levels reported by others for TbAlO 3 [15][16][17][18][19]. In 7 F 6 , Stark levels Z 1,2 , Z 4 , Z 5 , Z 7 , Z 8 , Z 9 , Z 12 and Z 13 are in reasonable agreement with published levels.…”

“…The different crystal-field splitting schemes for the 7 F J manifolds proposed by Sekita et al [15,16] and Joubert et al [17] for TbAlO 3 , and Arsenev et al [18] and Berg [19] for Tb 3+ in YAlO 3 , attest to the difficulties in making Stark-level assignments to the energy levels of Tb 3+ in the low symmetry site. While each manifold is split into 2J+1 non-degenerate Stark levels in C s symmetry, there exist Stark levels having nearly the same energy (quasi-doublets) within a manifold that are spectroscopically difficult to resolve.…”

“…In addition to the magnetic behavior of TbAlO 3 , there are interesting spectroscopic features associated with the material [14][15][16][17][18][19][20][21][22]. Intense fluorescence is observed from 5 D 4 to the 7 F J manifolds in TbAlO 3 .…”

Stark splitting scheme and an induced emission cross section of TbAlO3

“…6, the values in brackets are the results for Tb:YAlO 3 reported by Arsenev, Bienert, and Potemkin. 13 A considerable discrepancy for the splitting of the 7 F 5 multiplet can be seen. They reported the results only so that it is not possible to know how they constructed the Stark splitting scheme.…”
