摘要

Two series of Yb3+-doped silica glasses (YA and YAP) are fabricated using the sol-gel method,and their spectroscopic properties are investigated.The longest fluorescence lifetime of 0.96 ms is obtained in YAP2 and YAP3 glasses.The emission cross-section (σemi) and σemi × τ of Yb3+ in the YAP1 glass are 1.00 pm2and 0.94 pm2·ms,respectively.Co-doping with A1 and P decreases the hydroxyl group content in the glasses because of the reduction in non-bridging oxygen content.The lowest OH content in the YAP3 glass is 9.6 ppm.
