The upconversion emission spectra of Er3+ single doped and Er3+/Yb3+ codoped tellurite glasses with 974nm excitation were measured, the upconversion mechanism and the influence of Yb3+ concentration on the upconversion emission of Er3+ were discussed, the energy transfer efficiencies and coefficients between Yb3+ and Er3+ were calculated using the measured lifetimes.
