The Yb^(3 )/Er^(3 ) co-doped TeO_(2)-WO_(3)-ZnO glasses bubbling with different times were prepared. The infrared (IR) transmission spectra, emission spectra and fluorescence lifetime of Er^(3 ) at 1.5μm were measured. The quench effects of OH groups on emission intensity of Er^(3 ) at 1.5 μm as well as the relationships between fluorescence decay rate and OH group content were investigated. The constant k_(OH-Er), which represents the strength of the interactions between Er^(3 ) ions and OH groups, is approximately 17.0×10^(-20) cm^(4)/s, and is comparable to that for Er^(3 ) in Yb^(3 )/Er^(3 ) co-doped phosphate glasses.
