Abstract

Emission, absorption, and excitation spectra of 4f → 5d transitions of Ce ions in yttrium aluminum borate YAB crystal are reviewed and successfully reproduced by theoretical investigations. The Ce energy level diagram has been compiled after a careful analysis of the optical spectra. Theoretical calculations based on free ion and crystal field Hamiltonians are used to interpret the observed transitions. The 4f and 5d crystal field parameter permits determination of the engine states of Ce ion in YAB and then calculating the absorption line intensities as well as the effective section and the decay times.
