| Abstract: |
| The high phonon energy oxide of B2O3 is introduced into the Er3+/Ce3+ co-doped tellurite-niobium glasses with composition of TeO2-Nb2O5-ZnO-Na2O. The absorption spectra, 1.53 μm band fluorescence spectra, fluorescence lifetime and Raman spectra of Er3+ in glass samples are measured together with the calculations of Judd-Ofelt spectroscopic parameter, stimulated emission and absorption cross-sections, which evaluate the effect of B2O3 on the 1.53 μm band spectroscopic properties of Er3+. It is shown that the introduction of an appropriate amount of B2O3 can further improve the 1.53 μm band fluorescence intensity through an enhanced phonon-assisted energy transfer (ET) between Er3+/Ce3+ ions. The results indicate that the prepared Er3+/Ce3+ co-doped tellurite-niobium glass with an appropriate amount of B2O3 is a potential gain medium for the 1.53 μm bandbroad erbium-doped fiber amplifier (EDFA). |
