摘 要：Compositional-dependent heavy metal lead borate glasses doped with Tb3+ ions were investigated.Green luminescence related to main 5D4→7F5（543 nm） transition was registered under excitation of 5D3 state of Tb3+ ions.Based on excitation and luminescence measure-ments,several spectroscopic parameters for Tb3+ ions were examined as a function of heavy metal PbO content.Luminescence decay analysis indicated that the 5D4 luminescence lifetime of Tb3+ reduced from 2.83 to 1.42 ms,when PbO:B2O3 ratio was changed from 1:1 to 4:1.
