The niobate-phosphate glasses with high Er3+/Yb3+ concentration were prepared. The absorption and fluorescence emission spectra were measured. The effect of Er3+/Yb3+ ion concentrations on the spectroscopic properties was researched. The emission cross sections for 4I13/2 4I15/2 transition of Er3+ was calculated by McCumber theory. It was found that the emission cross sections around 1534nm increase and then decrease with the increase of rare earth ion concentrations. The maximum intensity of fluorescence occurs at the concentration of 6wt%. The effective emission cross section bandwidth was also discussed.
