摘要 yb^3+-Er^3+ co-doped Na20-Al2O3-SiO2-P2O5 glasses with different SiO2 content have been fabricated and characterized. Absorption and emission spectra were measured. Judd-Ofelt theory and McCumber theory are performed to analyze the measured absorption spectra. The Judd-Ofelt intensity parameters Ω4 and Ω6 decrease with increasing SiO2 content. The emission cross-section of Er^3+ decreases from 0.82×10^-20cm^2 to 0.76 × 10^-20cm^2 as the SiO2 content varies from 0 to 20 mol%. yb^3+-Er^3+ co-doped Na20-Al2O3-SiO2-P2O5 glasses with different SiO2 content have been fabricated and characterized.
