摘 要：<正>Yb3+-Er3+ co-doped Na2O-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 parametersΩ4 andΩ6 decrease with increasing SiO2 content.The emission cross-section of Er3+ decreases from 0.82×10-20 cm2 to 0.76×10-20 cm2 as the SiO2 content varies from 0 to 20 mol%.
