Abstract

Chalcogenide glasses of the composition 0.7Ga₂S₃·0.27La₂S₃·0.03Nd₂S₃ doped by 3 mol% of Nd³⁺ were prepared. The absorption and emission spectra of these glasses were compared to those of commercial ED-2 3.1 wt.% Nd-doped silicate glass. The absorption intensities of Nd³⁺ in chalcogenide glass are higher than in silicate glass due to the increasing covalency of Nd³⁺ in these glasses. Because of the low phonon frequency of the chalcogenide glasses nonradiative relaxations from the ⁴F_{5 2}, ²H_{9 2} to the ⁴F_{3 2} are lower than in other oxide glasses and so fluorescence from this state is observed.
