Abstract

Tb(3+) and Gd(3+) ions doped lithium-barium-aluminosilicate oxyfluoride glasses have been prepared. The transmission, emission and excitation spectra were measured. It has been found that those Tb(3+)-doped lithium-barium-aluminosilicate oxyfluoride glasses exhibit good UV-excited luminescence. The luminescence intensity of Tb(3+) ion increases for those (Tb(3+), Gd(3+))-codoped glasses. Energy transfer process from Gd(3+) ion to Tb(3+) ion is indicated.

摘要

掺铽（Tb(3+)）和掺钆（Gd(3+)）的锂钡铝氧氟化物玻璃已经制备。测量了它们的透过谱、发射谱和激发谱。发现这些掺铽的锂钡铝氧氟化物玻璃具有良好的紫外光激发发光。对于（Tb(3+），Gd(3+））共掺的玻璃，Tb(3+)离子的发光强度增加。表明了从 Gd(3+)离子到 Tb(3+)离子的能量传递过程。
