Infrared electronic transitions of Eu+3 in GdAlO3
- 1. Sao Paulo Univ., Sao Carlos (Brazil). Inst. de Fisica e Quimica
Description
Infrared 7F0 → 7Fsub(J) electronic transitions are reported for Eu+3 in GdAlO3. The low symmetry of the crystalline field allows the observation, for the first time, of transitions with J = 3, 4, 5 and 6. The spectra are explained by means of a crystal-field model where a Csub(s) term is added as a perturbation to the cubic field in order to take into account the lattice distortion. This model predicts energy levels which are in good agreement with the experimental data. (author)
