	Spectroscopic investigations of Er3+ doped Bi2O 3 -B2O3 -SiO2 glass (EI CONFERENCE) 会议论文 OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen B.; Wang X.; Wang X.; Wang X.; Wang C. 收藏 \| 浏览/下载：74/0 \| 提交时间：2013/03/25 From the optical absorption measurements the Judd-Ofelt parameters were computed using Judd-Ofelt theory. According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.
