Paper Abstract

Upconversion luminescence of Yb3+-doped and Yb3+ Ho3+-codoped oxyfluoride vitroceramics when excited by a diode laser operating at a wavelength of 960 nm is investigated. A strong 479-nm upconversion cooperative radiation luminescence, attributed to the coupled states of Yb3+Yb3+ clusters, is discovered. This result suggests an interesting and effective path to achieve compact blue upconversion luminescence. The presence of holmium in the Yb3+Ho3+-codoped oxyfluoride vitroceramics substantially reduces intensity of the cooperative upconversion luminescence.
