The effect of codopants on spectral-kinetic characteristics of luminescence of scintillation glasses doped with terbium ions

Research output: Contribution to journalArticle

Abstract

The effect of Ce3+ and Pr3+ ions on spectral-kinetic characteristics of luminescence of lithium–phosphate–borate glasses is studied. It is shown that terbium ion luminescence caused by transitions from 5D3 and 5D4 multiplets to the ground 7FJ term is detected in samples containing Tb3+/Ce3+ and Tb3+/Pr3+. It has been found that an increase in the concentration of cerium ions from 0.2 to 1 wt % leads to an increase in the intensity of main luminescence bands of terbium ions. In Tb3+/Pr3+ glasses, a decrease in the relative light yield is observed with an increase in the concentration of Pr3+ ions. Processes of energy transfer between Tb3+/Ce3+ and Tb3+/Pr3+ ions are discussed.
