Paper Abstract

Blue, even ultraviolet emissions and very strong green emissions have been observed in ZBLAN glasses codoped with Er3+ and Yb3+. The strong green emissions were demonstrated to be of sequential two-photon process, while the blue emissions be of multi-photon process, due to the strong sensitization of the Yb3+. The schemes of luminescence sensitization and quenching of Yb3+ to Er3+ were proposed.
