Abstract
Quantum yields of Ce3+ in borax glasses were obtained by the comparative method and by lifetime measurements. Energy transfer from Ce3+ to Tb3+ was detected in borax glasses from the excitation spectrum. The transfer probabilities were calculated from the increase in the Tb3+ fluorescence in the presence of Ce3+ and the decrease of the Ce3+ fluorescence in the presence of Tb3+. A linear dependence of the transfer probabilities was found with the squared sum of the concentrations of the donor and acceptor ions. This is consistent with dipolar mechanism and interactions of one Ce3+ donor with two Tb3+ acceptors, in view of the Fong-Diestler theory.
