| Abstract: | The emission cross section for the 2F5/2-2F7/2 transition of Yb3+ has been determined from absorption and emission measurements of some phosphate glasses at room temperature. The emission cross sections and fluorescence lifetime range from approximately 1.00 to 1.65 pm2, 0.3～2.0 ms, respectively. Systematic variations of the spectroscopic properties with glass composition can be used to tailor emission cross sections and fluorescence lifetimes. |
