In the present work, Ce3+/Tb3+ co-doped 60P 2O5-30BaO-10B2O3 phosphate glasses are prepared and their luminescence properties are presented. Under excitation at 303 nm, the Ce3+ ions singly doped sample show a novel red emission besides the UV one. The co-doped samples show enhanced Tb3+ ions emission with the increasing of Tb3+ ions concentration at the cost of Ce3+ emission. The mechanism of this luminescent behavior is discussed with respect to the relevant energy transfer process.
