Abstract
Formulation of radiative transition probabilities of 5d1→4f1 of Ce3+ and of 4f65d→4f7 of Eu2+ in a cubic crystal field is performed using pure 5d and 4f wavefunctions. The emitting state of Ce3+ is 5d(T2) or 5d(E). The coupled states of the 4f6(7F) core and 5d(t2 or e) are taken as the emitting states of Eu2+. Line strengths are calculated for all possible transitions, and transition probability distributions over the terminal states are obtained. The estimated radiative lifetimes of Ce3+ are about a half of the observed ones. For Eu2+, the calculated lifetimes are about thirty times as long as the observed ones. The theory suggests that Ce3+ has the largest radiative transition probability in the rare-earth ions exhibiting 5d-4f luminescence.
