Luminescence Character of Ce³⁺ in Rare Earth Borate Glasses

Ce³⁺ doped rare earth borate glasses (BLBL:Ce³⁺) were synthesized. The excitation and emission spectra and fluorescence decay curves of BLBL:Ce³⁺ were measured at room temperature. In BLBL:Ce³⁺ glasses, Ce³⁺ emits strong purplishblue light. The results of analyzing spectra and fluorescence lifetime show that there are two kinds of Ce³⁺ luminescence centres in this kind of rare earth borate glasses. Ce³⁺ doped rare-earth glasses is a kind of beneficial supplement for Ce³⁺ fluorescence glasses, system.
