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.
