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.
