  ABSTRACT: A series of Er3+/Yb3+ co-doped Sb2O3-WO3-Li2O glasses were prepared. Intense green upconversion fluorescence was observed near 524 and 544nm under excitation at 980 nm. The upconversion process was proved to be a two-photon absorption process. The upconversion fluorescence efficiency was enhanced by increasing introduction concentration of Yb3+ ions. The low maximum phonon energy of the glasses indicated that the glasses were good potential for upconversion optical devices.
