Intense green and red emission bands around 530, 555, and 670 nm, respectively, are observed in addition to near-infrared 830 and 925 nM less intense signals. Energy transfer processes and nonradiative phonon-assisted decays account for the population of the H-2(11/2), S-4(3/2), and F-4(9/2) emitting levels. The dependence of the red emission with the Yb3+ concentration is also analyzed. The potential application of the Er/Yb-codoped Ga2S3:La2O3 glass for upconversion based optical devices is discussed.
