Abstract

Glasses of the composition (70–X) mol.% Ga2S3 - 30 mol.% La2S3 - X Er2S3 (at X = 0, 1, 3) were synthesized  and the optical absorption spectra at room temperature were studied. Photoluminescence spectra in the 2.53 - 0.73eV range at 300 and 80K were investigated. Intense PL maxima at 2.25, 1.88, 1.45, 1.26, 1.13, 0.81 eV were found which correspond to transitions in the f-shell of erbium ions. The redistribution of the intensity of PL peaks with temperature was analyzed based on the energy transition diagram of erbium ions.
