Recent Advances in Simple Model for 4f-5d Transitions of Lanthanide Ions in Solids

摘要：

The simple model for 4f-5d transitions of lanthanide ions in crystals was extended to deal with the case of the octahedral crystal field, where for the t<,2> component of 5d orbitals the spin-orbit interaction could not be neglected due to incomplete quenching of the 5d orbital angular momentum. The energy levels for the 4f<N-1>5d configuration and the relative line strengths for the 4f<N> 4f<N-1>5d transition were calculated in detail. The result was applied to the interpretation of the low-temperature 4f-5d excitation spectrum of Cs<,2>NaYCl<,6>: Tb<3+>
