摘要

In the present work, Ce~(3+)/Tb~(3+) co-doped 60P _2O_5-30BaO-10B_2O_3 phosphate glasses are prepared and their luminescence properties are presented. Under excitation at 303 nm, the Ce~(3+) ions singly doped sample show a novel red emission besides the UV one. The co-doped samples show enhanced Tb~(3+) ions emission with the increasing of Tb3+ ions concentration at the cost of Ce~(3+) emission. The mechanism of this luminescent behavior is discussed with respect to the relevant energy transfer process.
