Novel luminescence behaviors of Ce3+/Tb3+ co-doped phosphate glasses

Abstract In the present work, Ce 3+ /Tb 3+ co-doped 60P 2 O 5 -30BaO-10B 2 O 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 Tb 3+ 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.
