摘　　要：The Yb2 O3 component was introduced into the Er^3+/Ce^3+ co-doped tellurite glasses with the composition of TeO2-WO3-Na2 O-Nb2 O5 to study the effect of Yb^3+ on the 1.53 μm spectroscopic properties of Er^3+. The X-ray diffraction(XRD) curve and Raman spectrum were measured to investigate the structure nature of synthesized tellurite glasses. The absorption spectrum, upconversion emission spectrum and fluorescence spectrum were measured to evaluate the improved effect of Yb^3+ concentration on the 1.53 μm band fluorescence of Er^3+. Results of the measured 1.53 μm band fluorescence intensity show a significant improvement with the increase of Yb^3+ concentration, while the total quantum efficiency reveals a similar increasing trend. The results of the present work indicate that Er^3+/Ce^3+/Yb^3+ tri-doped tellurite glass has good prospect as a promising gain medium applied for the 1.53 μm broadband amplifier.
