Glasses of 20 mol.% Ga2S3 – 60 mol.% GeS2 – 20 mol.% Sb2S3: Er2S3 (1–4 mol.%); Nd2S3 (2 mol.%) composition were obtained by the quenching technique. The optical absorption spectra investigation established that maxima at 655, 755, 810, 885, 980, and 1540 nm are the main absorption bands. Upon excitation of PL by radiation with λ = 805 nm, bands with maxima at 1070, 1350, 1540, 1700, and 2490 nm appear in the spectrum, which corresponds to the transitions 4F3/2 → 4I11/2 (Nd3+), 4F3/2 → 4I13/2 (Nd3+), 4I13/2 → 4I15/2 (Er3+), 4I9/2 → 4I13/2 (Er3+), 4I13/2 → 4I9/2 (Nd3+) in f-shells of both rare earth metals. The glass matrix’s high transmittance values and intense photoluminescence caused by Er3+ and Nd3+ make them suitable for designing optoelectronic devices for working in the near and mid – IR ranges.
