摘要
Compositional-dependent heavy metal lead borate glasses doped with Tb^3+ ions were investigated. Green luminescence related to main ^5D4→^7F5 (543 nm) transition was registered under excitation of ^5D3 state of Tb^3+ ions. Based on excitation and luminescence measurements, 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 Tb^3+ reduced from 2.83 to 1.42 ms, when PbO:B203 ratio was changed from 1:1 to 4:1.
