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.
