ChemInform Abstract: Luminescence Properties of Ce3+ and Tb3+ Doped Rare Earth Borate Glasses

Ce 3+ - and Tb 3+ -doped rare earth borate glasses were synthesized and their luminescence properties have been studied. The sample containing Ce 3+ ions has a strong purplish-blue emission and that doped with Tb 3+ emits a green light under UV excitation. The Ce 3+ ions in the host form two kinds of emission centers, owing to different lattice sites occupied by Ce 3+ in the host glass. In the Ce 3+ and Tb 3+ co-activated samples the Ce 3+ ions strongly sensitize the luminescence of the Tb 3+ ions.
