摘要：
The visible and near infrared emission spectra of Er-3/Tm3+-doped Ga2O3-Bi2O3-PbO-GeO2 (GBPG) glasses excited at 808 nm are experimentally investigated. The results reveal that 1.53 mu m emission were enhanced with an increase of Er3+ concentration. Furthermore, the incorporation of Er3+ into Tm3+-doped systems has also resulted in intense 522, 545 and 693nm upconversion emission intensity and an weak 660 nm red emission. The possible mechanism and related discussions on this phenomenon have been presented. The results show that Er3+/Tm3+-codoped GBPG glass may be a promising materials for developing laser and fiber optical devices.
